Tevez will always attract most of the attention when City play United, but the Argentine star has identified Silva as the man United should fear most.
'I think that David is the best signing we've made,' he said. 'David is the type of player who can win you the game. He can provide you with the sort of pass that puts you through one on one with the keeper.

'He is one of the best players we have in the squad today. I think he has freshened the team up a lot and brought a new dimension.

'There's no doubting we have the players here. The thing we need to do is build the team that the people and all of us want to see. I think that's what we need. It's always a big source of motivation to play alongside great players like (Edin) Dzeko and (Mario) Balotelli, like it is with David too.
'We have a forward line that can do a lot of damage to opposing teams. Right now, we've got Mario out injured and we have to wait for his knee to make a full recovery. But I think we're right in there battling it out for a Champions League place.
'It's what the team is aiming for and where the team ought to be. We've brought in a lot of new faces and they have needed time to settle into the squad. So at the moment we're still trying to build a proper team and I think if we finish in the top four we will have done really well.'
City are only five points behind United, and very much in the title race, yet Silva thinks a top four finish would make it a successful season.
'A good first season for me would be to qualify for the Champions League or to win a trophy,' he said. 'We will fight for the title and try to win the other competitions we are still involved with.
'I think within two or three years it will be normal for City to be playing in the Champions League, so I hope we can be on a par and challenge the best clubs around the world.'
