For Chelsea this can be a dream to beat Real Madrid in this situation both teams, currently, we know Real Madrid is in a good situation after they won the El Clasico and had a perfect performance there against Barcelona while they had players like Benzema shining at this match, while Chslea just started working with Lampard and comparing to Ancelotti he doesn't have enough experience to win this game.
Exactly, Lampard also have an experience to manage Chelsea in the past, but his strategy isn't fit with players and board member decided to sacked him. I know with Chelsea, he only has a job till end of season, but waiting for this Madrid need to make sure all of players ready to playing all out for the chance playing in UCL semifinals. Ancelotti and Madrid on better conditions, I think for the first leg, Madrid will trying to playing defensive with counter attack.
Previous experience was also a note for Lampard and now we have to look again at his strategy for playing in the UCL, will this be able to keep up with Real Madrid's game, while in other words the team from Spain is still victorious when playing in the UCL, so it won't be surprising later if they lose in this semi-final it's just that we need to know how Prank Lampard's strategy is with his current abilities to manage players in this big competition
If Chelsea can't defend at home then it will be difficult when they go to the Bernabeu because basically Real Madrid have great ability at home.
Even though until the end of the season when he was in the UCL, it was a tough task for Lampard.
The sad thing about Chslea is that they do not have a good atmosphere in their team because of the results they got in the premier league and the bad performance they had. My guess is that they will start out defensively against Real Madrid, causing Chelea to lose the game because of the strong forwards Real Madrid has in their team like Karim Benzema, but this won't help Chelea at all.
