There is a problem at Chelsea but I don't understand it either, maybe it's the technical team, maybe it's the players. If they don't solve it soon, I think they will have a big problem. Chelsea have good players but they can't make use of them. Maybe it's because everyone is doing their own thing. They can't play as a team or they can't score goals because they don't have the final touch.
I don't have much analysis of Chelsea, but maybe it's true that Chelsea don't play as a team. They have many new players in their squad and of course the problem of adaptation is likely to be an obstacle for the team to reach its best form.
Chelsea did not perform well in the first half where they made too many mistakes in defense. Their defense looked to be in disarray after Benzema's first goal, but Lampard was obliged to change his tactics in the second half. There was too much space for Real Madrid to take advantage of, that was the problem Chelsea faced in the first half.
