Arsenal boss Arsene Wenger says Manchester City must keep Robinho in order to attract more big names to Eastlands. Before yesterday's defeat of City, Wenger said: "He's a world class player.

"He went to Manchester City thinking he would be joined by many more players and you wouldn't be surprised if he'd had a hand in the Kaka story.

"A big, big player can also be a chance to bring in other big players because they think: 'he's gone, why shouldn't I go?' He's the first big buy or massive buy waiting for others.

"Frankly, I rate Robinho as a player but I don't know him as a person and don't know what he has been told. But when you look at the resources that City have, the newspapers will be busy with them in the summer."
