Real Madrid is in a complicated situation, the problem of injury is indeed a headache for Real Madrid while on other hand, they are still competing in the race for the La Liga title.
The second leg will be held at Stamford Bridge, of course, this is a plus point for Chelsea. The 0-0 draw was enough for Chelsea to qualify for the final so that Real Madrid had to fight hard with the ragged condition of the team. The ball is round, so anything can still happen .
I Agree Real Madrid is in a pinch right now and they sure all of their firepower to compete now because the home team have great form and regardless of Real Madrid's issue with injuries, but I am not saying that Chelsea can win we could see also see a scoreless draw or 1-1 draw just like in their previous game,
Right now it is a plus point for Chelsea being the event is on Stamford Bridge but I think that this is not enough and they would need to play aggressively and unexpectedly for Real Madrid to be shaken off, but they still need to play defensively just for assurance.
