Former Arsenal defender Martin Keown says Manchester City risk losing Sergio Aguero.

Keown wrote in the Daily Mail: "... City could end the season without a trophy, losing in the last 16 of the Champions League and failing to make a domestic final or retain their Premier League crown.

"So you could forgive Aguero for being tempted to move to one of the big two clubs in Spain or to Bayern Munich; somewhere he might feel he has a better chance of winning the Champions League.

"City must do everything they can to stop this happening.

"Since arriving in 2011, he has been City's most consistent player. Vincent Kompany is enduring a rough spell, Yaya Toure has issues with his temperament and David Silva is consistent but not a match-winner. Aguero is their main man."
