Don't be fooled, Arsene. Don’t be caught out by this impressive run of form and think everything is in place for a crack at the title next year. It is not uncommon to see Arsenal finish a season with a string of good results. Usually they rattle out a sequence of wins just in time to preserve their place in the top four but too late to affect the destiny of the Barclays Premier League. The same thing has happened this year. Chelsea were relentless from the first whistle and have had the title race firmly under control since before Christmas. Arsenal players celebrate after their extra-time winner against Reading in the FA Cup semi-finals last week . Alexis Sanchez jumps in the air and celebrates wildly after his second goal for Arsenal at Wembley . With a 10-point advantage, even if Jose Mourinho loses to Arsene Wenger for the first time on Sunday it won’t stop his side becoming champions. Next year, though, Chelsea won’t have it all their own way and no team is better placed than Arsenal to dislodge them. There is a different feel to their form and performances this time around and Wenger said recently he could ‘smell’ something happening. You just hope, however, Wenger and Arsenal’s board don’t get fooled into thinking they have got all the tools they need at their disposal. This is not the time to be complacent. This is the summer when Arsenal must go for it and make the big additions that will stop them being nearly-men. That is exactly what Chelsea did 12 months ago. After finishing behind Manchester City and Liverpool, Mourinho didn’t mess around. In came Diego Costa, who had spearheaded Atletico Madrid’s La Liga success, and a World Cup winner in Cesc Fabregas. They meant business. The money was big but the quality was proven and, after they were unveiled, everyone began tipping Chelsea for the title. We might be doing the same with Arsenal come August if Wenger, who has been criticised for spending Arsenal’s money like it’s his own, is similarly ambitious. Arsenal, it should be stressed, are not in need of major surgery and the spine of their team is now much stronger than at any point last season, when they only just held off Everton’s challenge to finish fourth. But there is still room for improvement. Arsenal manager Arsene Wenger talks to his players ahead of extra time at Wembley last Saturday . Chelsea manager Jose Mourinho looks in fine form during a press conference on Friday . Results have been impressive since David Ospina replaced Wojciech Szczesny, who had failed to show the required consistency. Ospina has played 12 Premier League games; Arsenal have won 11 and he has kept six clean sheets, but Wenger still needs to buy a new No 1 if they are to be title challengers. Petr Cech would be an ideal candidate to come in. Laurent Koscielny has steadied things in defence, with Arsenal winning 15 of the 18 games he’s played since January 1 but, to progress, Wenger needs another top centre back. Gabriel Paulista arrived in the New Year but it seems it was to provide cover for Koscielny and Per Mertesacker. Francis Coquelin has added bite to the midfield, but would Arsenal have enough to challenge next season if Coquelin is their anchor and Mikel Arteta is his back up? No. Why doesn’t he go for Paul Pogba, who looks set to leave Juventus? Wenger spent £42m on Mesut Ozil, so why not spend the same and more on Pogba. If they needed to sign Ozil two years ago, their need to sign Pogba this summer is even greater. Diego Godin of Atletico Madrid is 29 and at the peak of his powers. He would be ideal at the heart of the defence. Arsenal goalkeeper David Ospina pictured during a training session at London Colney last week . Chelsea goalkeeper Petr Cech warms up before Saturday's Premier League clash against Manchester United . Olivier Giroud, meanwhile, has provided a focal point up front. I like Giroud. He is an under-rated striker and, had he not missed three months with a broken ankle, his tally would be more than 14; he averages a goal every 101.93 minutes, the second best rate in the Premier League. Giroud is one of a number of good options Wenger has up front. Alexis Sanchez has been brilliant, while Danny Welbeck has played his part, but that should not stop Wenger looking to improve on what he has got. If a forward with the class of players he has had before, such as Thierry Henry or Nicolas Anelka, comes on the market, Wenger would have to move for him. Imagine what Luis Suarez, Sergio Aguero or Karim Benzema could do for Arsenal? I’m not saying Arsenal are getting to the levels of ‘The Invincibles’ but their form has me thinking they are getting closer. The 2-0 win at Manchester City in January could be a turning point. They made themselves difficult to beat rather than being open. Hopefully we will see more of this. Arsenal's French striker Olivier Giroud looks forward as he advances with the ball at Wembley .

Of course it has been frustrating that they have not challenged for the title since last winning it 11 years ago, and Wenger has not had a smooth ride. Fans turned on him after they lost at Stoke — and after the Champions League defeat to Monaco — leading to talk about Jurgen Klopp coming in. But some perspective is needed. Wenger has done a good job keeping Arsenal consistently in the top four — all their rivals have dropped out at some point in between — and by the end of next month, they could have won back-to-back FA Cups. How could you then get rid of Wenger? So one question would need asking: what are they waiting for? Both Manchester clubs will spend in the summer, but both those clubs have got far more problems to fix. City’s squad is old and needs big investment, while United will have the complication of being back in Europe. Wenger, then, could use the next window to call it on. The message it would send out to his players, fans and, most significantly, their rivals would be huge. It would let everyone know they were launching an all-out assault on the title. They would have to be taken seriously. Beating Chelsea on Sunday won’t alter things in the short term, but it will offer belief that Arsenal can challenge next season. What they do in the window will determine how big a statement they can make. Finding some special players could transform them.

Big guns missed out on a Fab freebie . Full marks to Aston Villa. They are a side rejuvenated by Tim Sherwood and absolutely deserved to beat Liverpool in the FA Cup semi-final. Jack Grealish understandably attracted most of the headlines for his outstanding performance but the role Fabian Delph played was just as important; his aggression, energy and left foot gives Villa balance in their midfield. Liverpool couldn’t cope with his aggression. Earlier this season, Delph was lauded for committing his future to Villa even when their position in the Barclays Premier League was threatened. He signed a four-year deal, which showed his character could never be called into question. What can be called into question, however, is the wisdom of some other clubs in the Premier League. Fabian Delph (right) celebrates after scoring for Aston Villa against Liverpool in the FA Cup semis . Delph, do not forget, was set to be out of contract this summer and a number of sides at the top of the table had their chance to sign a young England international for free. No doubt these same clubs will go out when the window opens and bring in at least one foreign midfielder, to go with the ones they signed last summer, and soon enough we will hear at some point next season that we don’t have enough English players playing for top sides competing in Europe. There will then be complaints from clubs saying it is impossible to buy English players because there is such a premium on them and they will argue that is why they are forced to look abroad for new signings. The Delph situation shows that sometimes such an argument is nonsense. He is now Villa’s captain and has been their best player for the last 18 months. His progress has been so impressive he is now a regular in the England squad and if he can add more goals to his game — like the one he scored against Liverpool — he could reach a very high level. Delph slots the ball past Liverpool goalkeeper Simon Mignolet in Villa's 2-1 victory at Wembley . If Delph does maintain his improvement, inevitably clubs will come looking at him. But if they want him, it will cost. For reasons only they know, they let slip a chance to get something good for nothing. Their loss is most certainly Villa’s gain.
