Patrick Vieira didnt join Man City from Arsenal. As for the 5 players who made the switch, only Nasri hurt. The other four were so replaceable, and in Adebayors case, he was actually sold - he even spoke about it. Wenger coming into the changing room telling him a bid has been accepted from Man City, he was completely blindsided by it. One of the most toxic players to have ever graced our club. Nothing to brag about paying 25m to take him of our hands, we thank you for it
More to the point. My argument was Arsenal would never swap Martinelli for Sterling. As to your point, project Arteta is coming together. Many young players in the first teams (Ramsdale 23, Tomiyasu 22, White 24, Tierney,24, Saka, 20, Martinelli 21, Odegaard 22, ESR 21. Only Partey, Lacazette and Xhaka are first team players over the age of 24. Lacazette and Xhaka will be leaving this season to so they will need to be replaced. We will need to sign about 4-5 net players in the summer window.
I am singerly confident Saka and Martinelli will sign contract extensions as seasons end. And if we have a transfer window like last season, I am confident we could aim for 3rd next season given the Chelsea turmoil, with the aim to get within 10 points of yourselves and City - target between 80-85 points. It can be done with a top striker.
