Chelsea travel to one of the most in-form teams in Europe on the back of a shock 2-1 home defeat to Sunderland. Atletico lead La Liga by four points and come into the semi-final in great form.
Stamford Bridge was the theatre to a different play than what Chelsea fans are used to seeing. Jose Mourinho seemed to take his eye off the ball, and in the Premier League, that rarely goes unpunished. With a 5 point gap between his Blues side and top of the table Liverpool ahead of the crunch game on Sunday, you could be forgiven for having your mind on other things.
Atletico though are a blur of pace and precision which will be succumbed by noise and hostility at the Vincente Calderon. Mourinho's mind cannot go wandering here.
Chelsea - Eden Hazard will miss this crucial first leg in Spain due to the calf injury that forced him off in the quarter-final second leg against Paris Saint Germain. Samuel Eto'o has been ruled out with a knee injury that leaves most thinking that Atletico's second son Fernando Torres will start against the club he supported as a boy.
Nemanja Matic and Mohamed Salah are cup-tied and will continue to be absentees for the Blues in this competition whilst Branislav Ivanovic is suspended.
Atletico Madrid - The much anticipated decision over whether or not Thibaut Courtois will be able to play has seemingly been answered by the man himself after he claimed he will play if selected. The many layers underneath this decision are still continuing.
Diego Simeone has a fully fit squad to choose from other than this decision that he has to make. Diego Costa is sure to start up front however having been in devastating form domestically.
