City monitoring Costa

Manchester City are weighing up a bid for Shakhtar Donetsk midfielder Douglas Costa, according to his agent.

The 20-year-old Brazilian has long been linked with Manchester United and was a guest of the club to watch the 1-0 win over Bolton in March.

But rivals City are now interested in the player, says agent Cesar Bottega, who added Serie A outfit Napoli are also monitoring his situation.

He told notiziariosportivo.com: "I have spoken a few times with Manchester City.

"They have shown interest in the player and are now considering whether to enter into a negotiation or not.

"I am planning a trip to Europe in a fortnight, but if something were to change I'm ready to leave earlier."
