Yaya Sanogo first in for Arsenal this summer

With the transfer window now re-open Arsenal have made their first signing but, surprise surprise, Arsene Wenger has felt the need to bolster his youth squad over world-class talent for the first team.

French striker Yaya Sanogo signed for the club on Monday from Auxerre and though I don't doubt his potential, I feel other areas within the squad need looking at with more priority.

The signing of the 20-year-old forward reflects the belief Wenger has in young players but this hasn't helped Arsenal win a trophy in the last eight seasons.

Recent media hype has linked the club with Wayne Rooney and Higuain, both of whom are well established players although there's nothing to suggest Higuain would settle in the Premier League and I'm not so sure about Rooney's attitude at times.

Still, Arsenal may not need another striker this season if Giroud, Podolski and Walcott find constant form alongside the attacking prowess of Santi Cazorla. 

The defence still remains the biggest area for improvement and with the transfer window now open, Wenger must sign an established defender quickly, with the right-back position and central defence key areas.

Still, I take nothing away from Arsenal's new signing, albeit another youngster, who has a chance to prove himself in North London. During his four year spell in the Auxerre ranks he scored 11 goals in 24 appearances and all Arsenal fans hope he can make a big contribution to the club during his Arsenal career.

Elsewhere Vito Mannone has left the club to join Sunderland, after eight seasons with Arsenal. He had his good moments...while others made for a laugh.
