Glad to see this thread still exist.
So close, yet so far away. 5 points behind Manchester City for the title. Pretty good for one of the youngest teams in the Prem. After last season, expectation was to finish 4th, 3rd at the highest. They exceeded that, having the lead for most of the season. Punch to the gut to not win it. No doubt the Saliba injury had a huge impact, an impressive first season for him after spending a couple years on loan. Jesus had the hot start, but the injury from the WC really slowed him down. Odegaard, Martinelli, and Saka had very good seasons, though the latter 2 had some inconsistent moments down the stretch.
On to the summer. Undoubtedly, the biggest summer of the Arteta reign. Have to think the back stays the same (White, Saliba, Gabriel M., Zinchenko), they'll likely look for depth at the fullback positions and may look for another CB. Midfield is the big question, outside of Odegaard. I would think they attempt to sign 2 starting midfielders. Xhaka looks to be sold to Leverkusen. The last 2 seasons have probably been the best Xhaka has played for Arsenal. Partey might be going elsewhere, may be staying. Jorginho is another older player, but I think he's a good fit for a backup rotation piece. Not sure I'm a fan of the Gundogan rumors, just again, given the age of some of the players in the 6/8 roles (Partey if he stays, Jorginho, and Elneny is still under contract). We'll see what happens.
