Chelsea v Barcelona: Pep Guardiola dismisses talk of Stamford Bridge job as 'fantasy' "It's imperative to play a pressing game," said Frank Lampard. There's no way you can be passive against them. We'll have a game-plan to attack them but the main thing is a sense of urgency in your defenders. When you give Xavi, Iniesta, Messi - I could go on and on - time they'll hurt you. We have to pressure them in all areas of the pitch. Yet Messi, the little magician with the big heart, has never scored against Chelsea, a statistic that brings delight to the Shed but ignores that the Argentine has lifted his game to Olympian heights since 2009. The simple fact is that Messi has scored 63 goals this season and is a phenomenon, making even Cristiano Ronaldo, who is enjoying a stellar season, appear a mere mortal. "Inevitably, every time you turn the telly on, Messi scores two goals standard," said Lampard. We're proud he hasn't scored against us. But statistics and records go out of the window the way he's playing. Individually he's proved himself to be the most dangerous player in world football. And Barcelona boast Xavi, who conducts the Catalans' celestial orchestra. And Iniesta, who knits play and scores. And Cesc Fabregas, who is scheming in midfield one moment, raiding into the box the next. And Dani Alves, the right-back who becomes a right-wing in the blink of an eye. And Alexis Sanchez, the swift Chilean. "We're under no illusions," said Lampard. I like the tag of being underdogs. It's always refreshing if you believe in yourself, and we do. You don't want to take too much fear into the game. You can talk yourself into fear by talking Barcelona up. But we'll have to be at our best, because we're taking on the best. Chelsea have a chance. If the whispers are true, and Fernando Torres starts ahead of Didier Drogba, Chelsea will need the Spaniard to give the performance of his life, certainly a display superior to anything in sustained excellence he has given in his disappointing career at the Bridge. Torres will certainly be motivated, playing against so many compatriots, and he must look to exploit Javier Mascherano's occasional rashness in the tackle. The Argentine is a booking away from missing the Nou Camp leg. If Torres eases up, then Di Matteo can turn to Drogba, who Barcelona players like Cesc Fabregas kept referring respectfully to yesterday. Guardiola made a most amenable guest yesterday. Whether it was mind games, diplomacy, genuine belief or his innate politeness, Barcelona's coach lavished praise on Chelsea. "Ivanovic, Terry, Cole, Lampard, Essien, Drogba are players who have had thousands and thousands of adventures," he said. They've changed the manager and a couple of players, but the same players are largely there. They have the same spirit, the same soul, the same foundation. I do admire that generation of players, who have done so well over the last seven years and have got into so many semi-finals and finals, and competed in the Premier League so well. I am struggling to see how we are going to hurt them and how we are going to create chances to score goals. We shouldn't forget they've been very consistent here in this stadium, winning all five of their (Champions League) games. As well as the moisture from a brief hailstorm, grievance still hung in the air at the Bridge. Bitter memories still rankle of that fractious night in 2009, of Tom Henning Ovrebo denying Chelsea penalty claims and Drogba screaming abuse down a camera lens. Lampard has not forgotten that wild night, not forgotten that Chelsea keep reaching semi-finals, but have won only one of five in the last eight years, against Liverpool in 2008 and then lost the final in Moscow to Manchester United. "I wouldn't lie and say it's not disappointing to have reached so many semis and a final and not won it," said Lampard. But it is the greatest competition in world football and it gets harder every year. There are teams from Spain, Italy, Germany all improving all the time. So no one has a divine right to win it. Some of my worst moments in football have been losing semi-finals, the Barcelona game (in 2009) probably more than ever given the circumstances. You have to bounce back. We hope the Champions League will one day come to us and we'll win it. Lampard emphasised the need for discipline. "Keeping 11 on the pitch is crucial," said the Chelsea midfielder. Sergio Busquets has a reputation for the theatricals but Guardiola dismissed the "diving" criticism from the likes of his former player, Zlatan Ibrahimovic. Mr Ibrahimovic knows better than the rest of the world the level of our team: take the ball, pass the ball; take the ball, pass the ball. Diving is for the swimming pool. Chelsea are about to take the plunge into forbidding water. Form guide Chelsea have lost just one of their last 12 matches and have not lost at Stamford Bridge in their last six league matches. Barcelona have won all their last 11 games in La Liga and their last six away matches. They beat Levante 2-1 last Saturday. Betting odds (Ladbrokes) Chelsea to win 4-1 Draw 5-2 Barcelona to win 8-11
