People already know my thoughts about Debuchy. He distinctly average, he's the weakest senior defender in the squad.
He's early season performances very suspect. He fell into the overly attacking fullback typecast. Constantly going forward and leaving too much space behind. At the age of 29 I expected him to come with the experience to know basic positioning and defensive discipline. The guy obviously been running wild down the right flank through out his career, It's petty easy to tell he's hasn't transitioned as well as can be expected to top level club football.
The price we paid does not match the output from Debuchy. Say what you like about his freak injures, I know they weren't his fault but that doesn't matter, the reality is we've wasted £12M on a player we expected to come in straight away and do a job. We'll be lucky to get £2M from Lille
Maybe writing off one season would be acceptable if he was 25/26 but he'll be 30 at the start of next season not sure if he can offer Arsenal anything significant really. Bellerin for all his faults and holes in his game we can see he is leaning and improving I wouldn't like to see Debuchy start over him tbh
On top of this we should have kept Sagna instead of paying more for an inferior RB. Sagna could have become a quality CB plus he would have had alot more experience to offer Bellerin through mentoring.
