Frank Lampard hails the return of Chelsea's work ethic under interim manager Roberto Di Matteo Asked about the interim manager getting the job on a full-time basis, he said: "That's a question for the club but he's done brilliant - no one can deny that when you look at the results and the turnaround, the atmosphere, the confidence running through the club. I think the fans have all related to him, being an ex-Chelsea player. One defeat at Man City means we have given ourselves a chance by closing the gap on fourth place, we are in an FA Cup Final and now 90 minutes away from the Champions League Final. Chelsea's history of near misses in the Champions League is a source of inspiration ahead of the second leg of their semi-final with Barcelona at the Nou Camp on Tuesday. Didier Drogba's goal has given them a 1-0 lead going into that game and Lampard believes that memories of their four semi-final defeats, as well as their loss to Manchester United on penalties in the 2008 final, is driving on the experienced players in the squad. "You use that as a source of inspiration and determination to get to the final," he said. We want to win this competition along with a lot of other clubs and the fact that we have been so close in Moscow and semi-finals that didn't quite work for us, then of course your desire grows every year. Chelsea were eliminated by Barcelona on away goals in the 2009 semi-final but did manage to hold Pep Guardiola's team to a goalless draw in their own stadium, a result that would see Chelsea through this time. "I think they have improved since 2009, the movement and the passing," Lampard said. We worked hard at Stamford Bridge and we had a little bit of luck along the way. We believed that we could get a result and we got a very good result. We didn't play them last year but the standards they set last year and this and the way that they play, for me they are the best club team there has ever been, in my lifetime for sure, because of the all-round team and the quality of the players they have got. Having played there, having that experience, will help. They have improved since we last played them, so it is going to be a very, very tough ask. So maybe the experience will help but it will mean nothing on the night if we don't turn up and put in the shift. It is a very tough game, no doubt about it, but I don't think it is intimidating. I think it is exciting. We were looking at going out to Napoli about six weeks ago, the fact that we are in this position to give ourselves a real fighting chance is great. Having been disappointed at this stage on so many occasions, Lampard was keen to guard against complacency. I think the key will be two things; work rate and focus, because I think you have to concentrate against them. All the players were saying in the dressing room that their movement is first class, plus the speed of their play. So you can't shut your mind off for a minute and you have to work hard to cut space off all over the pitch. And then we have enough ability in the team that you hope you can create something on the break.
