Chelsea can't challenge Real Madrid I'm very sure of that , Real Madrid don't joke with champions league even when playing with a team with the same quality of performance. Chelsea will only as much they can try but it won't stop Real Madrid from winning the game. Real Madrid already knows that Chelsea can't win them, this has already given them more confidence of winning the against Chelsea. Real Madrid already has experience of winning games, Chelsea are trying to get better and it won't be possible for them to win against Real Madrid.
Anyone that watched the match between Real Madrid and Barcelona will sympathies with Chelsea. A club that is coachless playing against a well-organized team with one of the best football technicians in the world. Chelsea has all it takes in terms of quality players to withstand the Real team but the players are not well coordinated to enable them to get winning goals. Chelsea has no chance to win this game except they are favored by mother luck. I don't know how true it is, I heard that Frank Lampard has agreed to manage Chelsea as an interim coach till the end of the season. Chelsea has a history of winning the Champions League with interim or newly appointed coaches. Lampard now has the opportunity to showcase what he has learned from his sack experience.
although Lampard managed to make Chelsea's players play better. but their opponent is Madrid, obviously, it will not be easy to resist Madrid's aggressiveness in making goals.
indeed Chelsea has good players, Potter's failure should be a lesson for Lampard to form his squad. against Madrid, maybe Chelsea will finish here. but we can see how Lampard will progress in the remaining matches this season. if Chelsea plays better, club management should consider Lampard to be the main coach at the club.
