Defending champion Real Madrid faces familiar foe Atletico Madrid for a place in the Champions League semifinals while Barcelona appears to have its place already booked.

The Madrid rivals produced a stalemate in the first leg of their quarterfinal, leaving everything to play for at the Santiago Bernabeu stadium on Wednesday in another rematch of last year's final. Also Wednesday, Monaco needs to shake off poor home form for the visit of Juventus after losing the first leg 1-0 in Turin. Barcelona has one foot in the semifinals with a 3-1 away win over Paris Saint-Germain ahead of the return leg on Tuesday. Also today, five-time winner Bayern Munich faces an uphill struggle to reach its fourth consecutive semifinal after losing 3-1 at Porto last week. At least the Bavarian side can count on enthusiastic home support.
