Paul Merson is of the belief that Arsenal needed more than just a goalkeeper in the summer transfer window.

Arsene Wenger signed only Petr Cech prior to the new campaign which is a situation former Gunners star Merson cannot fathom when you take into consideration that they finished 12 points behind champions Chelsea and also have around £200million in cash reserves.

Merson told Sky Sports that he strongly feels Wenger should have gone after a quality goalscorer in a bid to strengthen the club's title hopes and is puzzled as to why no offer was made for Real Madrid star Karim Benzema.

Merson said: "Why have Arsenal finished that many points behind Chelsea last season and only signed a goalkeeper?

"They should have gone for Karim Benzema. Arsene Wenger in the summer compared Olivier Giroud to Benzema, but the Real man would get more goals.

"He should have put in a bid for £70m, and if he didn't want to come then so be it, but at least Wenger could have shown his ambition to the fans.

"Wenger sees what players are worth and doesn't want to pay more, but modern football is clubs demanding more than a player is worth. You don't get players for cheap anymore.

"You can't have £193m in cash reserves and not use some of it to win the league.

"I'm a great believer in evolving. We saw it with Manchester City after they won the league, they didn't change the team much and they fell short. The hardest thing in the world is improving year on year, or getting to the top and staying there.

"If one of the centre-halves or strikers gets injured they're in trouble. Arsenal will not win the league with Theo Walcott up front as the main focal point. They need a bigger focal point."
