Real Madrid will be playing against Borussia Dortmund this Champions League Quarterfinals. The first leg will be played at the Santiago Bernabeu (Robert Lewandowski will not be available for that game). Remember that Ilkay Gundogan will not play the tie either.
The players will be looking for some revenge after being knocked out of the competition by that same team last season. It's true that everybody expected Real Madrid to advance to the Final last year as well, but this Borussia Dortmund team is certainly not the same one.
Bayern Munich will be playing Manchester United, while PSG will face Mourinho's Chelsea. Barcelona will have a tough test against Atleti too, playing the second leg at the Calderon.
Expect Real Madrid to advance to the Semifinals if they get a good result at the Bernabeu, but the Semifinals will not get any easier. Consider yourselves lucky. It was a really tough draw and Borussia were one of the two weakest teams.
