He said: â€śWe know itâ€™s going to be more difficult than in Manchester because United will arrive here looking for victory and needing goals.
â€śBut the loss of Rio Ferdinand could be very important for them. Also, Cristiano Ronaldo wasnâ€™t decisive in the first leg and now he has to play under all the pressure and atmosphere our ground will generate, while knowing he could easily be going out of the competition.
â€śObviously we have to avoid making errors, but weâ€™ll be happy to maintain our concentration and keep the game goalless. We have our own dreams.
â€śThe first leg was the best match of my life.
â€śBut as a team we showed why Porto are the Portuguese champions and that we can defeat anyone in Europe.
â€śUnited were not better than us at Old Trafford â€” and they know that.
â€śWe can make it a very nervous night for them.â€ť
