Manchester City boss Roberto Mancini was delighted with their Europa League win at Porto.

Mancini hailed his "fantastic" players after they came from behind to take the advantage after the first leg of the last-32 tie.

Sergio Aguero came off the bench to score the winner six minutes from time after an Alvaro Pereira own goal had cancelled out a Silvestre Varela strike.

Mancini said: "I think it was a good result because it is difficult to win here.

"I think we won this game because we played very well and didn't give more chances to score to them.

"I think the guys were fantastic."
