Chelsea in bullish mood for Champions League test against Barcelona despite likely absence of David Luiz "I think we thrive on these games," said Lampard. We all live right these days. I'm certainly not going to ask to be rested. Lampard said the players had taken huge confidence at how they seem to be producing their best form at this critical moment of the season. Drogba even bullishly claimed the semi-final against Barcelona was a "50-50" tie. "Sunday was a symbol of Chelsea at our best and people know what we're about," said Lampard. We were very strong all over the pitch. Didier came up with something special. He put in one of the performances of the season. It was an amazing goal and the second half was probably as well as we've played all season. If we play the way we did against Tottenham, with the focus and determination plus the ability we have in our team, we have to believe we have a chance. I don't mind if people write us off. We can't show too much fear against them. We have to respect them but we have to take them on and play the way we did against Tottenham. Lampard, though, admitted that Lionel Messi had already surpassed Diego Maradona as the greatest player he had seen and is expecting the Argentine to be even more difficult to contain than in the 2009 Champions League semi-final between the two clubs. "We won't go back to 2009," said Lampard. They've probably moved on from 2009 and we've changed as well. Messi's a different player to 2009. He was a fantastic player then but now he's improved even more. The level he's taken his game to is something I've never seen before. I grew up on Maradona, who was my idol as a player, but Messi has taken it even further. To score 70 goals, which he'll probably end up with this season, that's crazy. Absolutely unbelievable. Chelsea's renewed confidence was also outlined by Drogba. "We have some good memories as well against Barcelona so it's a 50-50, even if they are said to be the best team in the world," he said. There are two games - anything can happen. Drogba also appeared to indicate that he would be leaving this summer when his contract expires. "It's not about my last year here," he said. Nicolas Anelka, who has joined the coaching staff of Shanghai Shenhua, said on Monday that he wanted his former team-mate to follow him to China. Meanwhile, Andres Iniesta, who scored a last-minute equaliser at Stamford Bridge to send Barcelona to the final when the teams met in 2009, identified fellow Spaniards Juan Mata and Fernando Torres, plus Lampard and Drogba, as Chelsea's key players. He said: "Mata is so dangerous when he drifts in front of opposition defences and he has that great left foot. He can really make the difference. And Fernando Torres is one the best forwards in the world. Goalscoring runs come and go but he has always scored an infinity of goals. What makes Lampard and Drogba dangerous is that they have been the best in their position during their entire careers. It is not about their age, it is about the fact that they are great players.
