Arteta doesn't have good backup players when the squad feels tired or injured, of course Arteta doesn't have other players to rely on, even though Arsenal could have won the league this season, unfortunately Arteta didn't really manage their players at the end of the season, Arsenal have been around for so long top of the table before but unfortunately at the end of the season they looked tired and inconsistent.
Arteta tried in the just ended season but Arteta those not have much experience that was what stopped him from winning league for Arsenal, how will their be a team and you don’t have back up, toward the ending of the season, from Arsenal performance drop, you will know that those players are tired, how will you keep on using the same squad from the beginning of season till ending, they will get tired and that was what happened to Arsenal, Arteta tried but if am to blame anyone why Arsenal didn’t win the league, then am still going to blame Arteta for that. But am sure he will correct his mistakes before the next season will start, but if he those not, then Arsenal won’t really perform well next season.
