"The team has been performing really well. Everyone involved in the squad has showed the quality they have," said the boss.
"Against United we didn't know until just before kick off that Sami Hyypia was playing. We also had to move Jamie Carragher to right back but despite these problems the defenders were outstanding.
"Fabio scored a great free kick and showed the quality he has. We know if he can stay fit he is a great asset for us. I remember telling Stevie and Carra when we signed Fabio that he was great at set-pieces, and so it was fantastic to see him score at Old Trafford.
"When I went to Valencia and watched some videos I saw that Fabio never lost the ball. He is a quality player and is playing very well at the moment.
"It was also good to see Dossena score two goals in two games and I thought Lucas played very well against a quality midfield.
"It was a very positive game and you can talk about all of the players making a contribution. It shows the quality we have."
