Former Arsenal star Paul Merson isn't convinced by Manchester City's swoop for Swansea City striker Wilfried Bony.

Merson says City have other areas in need of strengthening.

He wrote in the Daily Star: "Bony is not just a goalscorer. He holds the ball up well and brings other players into the game.

"He has also scored more goals than anyone else in the top flight over the last year so he has proved that he can do it in England.

"When I watch City I don't worry about them going forward, even without Sergio Aguero. Besides, he is coming back soon. But I do worry about them defensively.

"They paid a lot of money for Eliaquim Mangala but he doesn't look like he's worth half of his transfer fee at the moment - and Vincent Kompany has been out injured.

"When you play City, you know they will always give you a chance."
