The North London club had the fourth lowest net spend in the Premier League.
“We’re happy, Petr Cech is an amazing signing for us,” said the 25-year old, in an interview with talkSPORT.
“He’s already shown his quality – in the first half of that Liverpool game – (he showed) what an amazing keeper he is, and how much of an asset he will be to the squad.”
The Gunners lack of activity beyond Cech isn’t a cause for concern for the OX, and he cited the players still to return from injury as evidence of Arsenal’s strength in depth.
He added: “If you look at the rest of our squad, we’ve got great depth and a lot of quality, and if you look at the likes of Danny Welbeck and Thomas Rosicky - soon to come back – we’ve got some really good options.”
While the Arsenal squad does indeed have depth generally, there are still clear positions where quality alternatives are lacking.
The big one is, of course, up front and while Theo Walcott can function through the middle in Olivier Giroud’s stead – neither are the world-class hit-man required to clinch a Premier League or Champions League title.
The Gunners seem to forever be linked with the likes of Edison Cavani and Karim Benzema and until a striker of that ilk arrives to compliment their glittering array of attacking midfielders, success will be limited at the Emirates.
Centre-back is the other long-term problem area, and the fielding of Gabriel Paulista and Calum Chambers against Liverpool speaks volumes.
Arsenal escaped without conceding on that occasion, but a more clinical side would have scored three or four and Arsene Wenger’s failure to address this obvious issue is a strange move.
Defensive midfield back-up for the impressive Francis Coquelin would also have been a welcome, if not crucial addition, but Wenger's stubborn approach to the transfer market could end up costing the Gunners again.
