Former Arsenal striker Alan Smith feels manager Arsene Wenger is failing the club in the transfer market.

The Gunners started their victory against Newcastle United on Saturday evening with Mathieu Debuchy playing out of position in the centre of defence and 19-year-old Hector Bellerin playing at right back.

"They knew Koscielny had a problem with his achilles, that has flared up several times already," Smith said on Sky Sports ahead of the match.

"They knew Vermaelen was leaving. So why haven't they brought someone in? I think the recruitment is something they need to look at because they are not decisive enough. Arsene tends to change his mind a lot."
