Manchester City 4 Watford 2: match report Although none of the Agüero goals would feature in his most outstanding efforts, the trio highlighted the fact that, once in the opposition penalty area, there may not be a more prolific converter of chances in English football. On the hour, the Argentine was on hand to steer the ball into an open net after Jonathan Bond had blocked well at close range from Edin Dzeko, who connected with Aleksandar Kolarov's centre. Eighteen minutes later, Agüero finished superbly, steering the ball over Bond into the top corner after Dzeko had picked him out following an excellent counter-attacking run from Jesus Navas. He completed his team's and his own scoring deep into injury time, rising at the far post to head home a cross from Navas that left the scoreline flattering the home side. Prior to that, on 87 minutes, the tie had been effectively settled in an unfortunate manner when Kolarov's speculative shot from over 25 yards squirmed through the grasp of Bond and over the line. It was an unkind manner for the Watford goalkeeper and his team to exit the competition but a sign, perhaps, that on top of the financial advantage City clearly hold over all-comers, they can also count on a large slice of luck when needed. "It's the same question the media asks every week," said Pellegrini when quizzed about the prospect of four trophies coming his way in his first season at the Etihad. I don't know what will happen in the future. I'm absolutely sure if we play as we did in the first half, it is impossible. If we play as we did in the second half, maybe we can continue in all competitions. We're not thinking about that. We've had a cup week, continued in the Capital One Cup and taken another step in the FA Cup. Now, we have four games in the Premier League and will continue to try and win every game. The beaten Watford manager Giuseppe Sannino, however, could be less cautious in analysing the team that had just knocked him out of the competition. "I used to watch Manchester City on TV, tonight I saw them from the touchline," the Italian, who took over at Watford in December, said. They have a lot of very, very good players. Yes, I think they can compete for all four titles they are looking for. But you know football is very strange so they have to be focused every single game. City were certainly not focused during a first half in which a three, or even, four-goal deficit would not have been unreasonable, and this for a team who have trailed at home to English opposition for a grand total of eight minutes this season - one to Everton, seven minutes to Liverpool. After 20 minutes, Marco Faraoni slipped the ball forward for Deeney whose through pass was perfect for Forestieri to run on, compose himself, and give Watford the lead with a shot through the legs of Costel Pantilimon. Once more exposing flaws in the home defence after 28 minutes, Forestieri and Ikechi Anya made swift, slick passes to play in Deeney who, again, showed great composure in comfortably beating Pantilimon. There was also a reasonable penalty appeal after Anya went down under a challenge from Pantilimon and Daniel Pudil ended the first half by lashing a shot into the side netting as Watford once more took advantage of Richards weakness down the left flank. "If I could change 11 players at half-time, I would have changed all of them," Pellegrini said. It was more to do with attitude and intensity than performance of individual players. The whole team didn't do things we normally do. But in the second half, we played with another tempo, another pace and we continued to play the way we have the whole season at the Etihad.
