"Everybody's talking about Manchester United, but in their last away game they disposed of West Brom, winning 3-0. David Moyes has got so many players to choose from that fatigue won't come into it that much, because he can change the side that played against Olympiacos with top international players if he wants to. I think it's going to be a really tough game and we'll have to be on top of our form to get anything out of it."
