Although he is no longer in the team, Xhaka also improved a lot from coaching by Arteta and team.

I agree with james . the whole team has improved .RAYA. TOMIYASU.

Leandro Trossard, Kiwior etc. The whole team is well coached

Saka was already playing in the wings

Ya and even GabrielJesus

To me Saliba W.

Not to criticise, but would have thought Declan in his advanced(left 8) position, with his Bournemouth burst from the middle in the 90+ minute, OR his pirouette on the 18 yard box(can't remember who twas against), would be attractive to you especially his evolve from a 6 to the current present 8 with his prowess/power attacking the box late...... All this built on an astute defensive acumen(with him running towards his own box n putting in a tackle to break up an opposing teams attack, n have us racing back into the opposing half, in a dangerous move spurred on by his hard raw runs(seldom tires, n IF he does, he just seems to find the next gear) that seem to tear the ground with defenders scampering to get back into formation ..... N I could go on n on, his crosses, n headers to.... Adding to his goals n assists..

I’m gonna be honest, the only Arteta has improved in my opinion are Gabriel Magahlaes and Saka and I’ll state why. When Arsenal signed Ben white the amount of teams that wanted him at the time were numerous (Man City, Chelsea, Man Utd, Liverpool, Leeds[Bielsa]) cause of time at Leeds. We already knew B.White could play multiple positions based on the way Bielsa played him. The only reason nobody wanted to buy him at the end was because of the price tag so I’d say he’s somewhat fulfilled his potential. Kai Havertz has had a decent full season at Arsenal. He’s in red hot form now but he was signed as an no.8 not a CF just as a reminder. Asides for that for the amount of goals he’s meant to have scored, similar to Isak, he’s neither over or under performing so I wouldn’t necessarily say Arteta has improved him. He’s playing in a position he’s been playing in for years for a team that isn’t changing their managers and/or team almost every season. Odegaard prior to coming to arsenal was already considered good that that was seen at his time at Sociedad. He would be at Madrid if Modric and Kroos weren’t still performing at a world class level despite their ages. Similar to B.White odegaard is fufilling his potential he has drastically improved like Haaland’s first season at Man City or Salah’s first season at Liverpool. I still feel Odegaard can a little more when it comes to improving his R foot, having a little more impacts to games, assisting goals with better passes, etc
