Manchester United ace Wayne Rooney is excited to be facing Arsenal in the Champions League semis.

"We just had to come here and win the game. Once we went 1-0 up we defended very well and never really looked like conceding," the striker told Sky Sports News after victory at Porto.

Of the clash against Arsenal, he added: "It will be a difficult game. They are a good team of course. Hopefully it will be two exciting games.

"It [retaining the trophy] is something we are really focused on. It is a great opportunity for us to do that, having reached the semi-finals."

United full-back Patrice Evra added: "It will be a difficult game because Arsenal have a lot of big players back and they are in great form."
