UEFA Champions League QF/SF/F

here is the schedule:

Arsenal/Villareal vs Manchester United/FC Porto
Liverpool/Chelsea vs Barcelona/FC Bayern

good draw for Man Utd.

Here is something about FC Porto:

Porto (33/1): Group G winners, beat Atletico Madrid on away goals, 2-2 on aggregate in last 16; UCL top scorer 08/09 - Lisandro (6); Reds’ head-to-head in Europe: P6 W2 D2 L2 F11 A9

"This is the furthest the Dragons have ventured in Europe’s top club competition since they won the tournament in 2004, when they knocked United out along the way (lest we forget). Manuel Pellegrini’s side have already travelled to England in this season’s campaign and returned to northern Portugal nursing the wounds suffered in a 4-0 defeat to Arsenal in September. The 2-0 victory over the Gunners in the group stage’s final matchday was some form of revenge and guaranteed top spot in Group G, but Argentinian captain Lucho is fully aware that his side will start second favourites no matter who they draw in the quarter-final draw. “We'll take whichever team comes up,” he said after the win over Atletico Madrid. “They will all be difficult to play against. First we owe it to ourselves to enjoy this moment, and then we'll start working towards the next stage."
