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.
