4. Christos Tzolis
Christos Tzolis is a player who, like Saka, started the season well but has slowly deteriorated since his hot start. Unlike Saka, though, Tzolis doesn't have the banked credit that his counterpart on the other wing has.
Tzolis arrived with big boots to fill. Martinelli and Trossard were sold, with the Greek international tasked with replacing both cult heroes.
We saw in his early moments at Arsenal that he was a direct winger who only had an eye for involving himself in goals. Fast forward to the end of September, and we learned that he was simply playing against Coventry. That piece of context is vital, in hindsight.
Still, the signs are there. Tzolis is clearly capable of being a great winger for Arsenal, but he needs to return to that direct approach out wide.
Tzolis is not going to start every single week. He can rotate in and out of the team, particularly with Eze helping him out as a backup. This should keep him fresh, but from Arsenal fans' perspective, they need to see better from him when he's starting.
5. Kepa Arrizabalaga
Nobody wants Kepa Arrizabalaga to play. Whenever he's named in the team, the collective response is virtually the same: One big sigh.
However, that's exactly the fuel Kepa needs to turn it around. If Arteta goes down the route of starting Kepa in cup games, which seems to be the case again this season, then Kepa has a point to prove.
Illan Meslier is lurking in the shadows this season, which was not the case last time out. Any mistake that Kepa makes, and Meslier will be cracking his knuckles at the thought of getting into the team.
Kepa cost Arsenal in two cup competitions last season - the Carabao Cup and the FA Cup. Arsenal are yet to play an FA Cup game, but in their sole Carabao Cup fixture, Kepa was the starting goalkeeper, conceding twice to Ipswich Town away from home.
