The move surprised us all.Calum Chambers had just been awarded a new contract extension. It was surely a show of faith in the player from new coach Unai Emery, to say that the defender is part of his future plans and will be an important fixture in the squad.Yet, a week later, we had sent him on loan to Fulham for the entire season.Sokratis and Mustafi are forming our first team defence right now with captain Laurent Koscielny out until November. When he returns, then most likely Mustafi will be benched, with Rob Holding as back up. It would have been an almighty scrap for Chambers to force his way through, but on the evidence of the last two seasons, can we say he is below the players above?Two seasons ago he spent the season on loan at Middlesbrough and while they were relegated, Chambers performed admirably and was part of the eleven for the duration.Last season saw him slot in when Koscielny was injured and again, he displayed the attributes we needed. He had pushed himself up and worked for it.Now, he is at Craven Cottage, and the last two games he has spent on the bench.Granted, Fulham have gone without defeat in those games, but the opposition were vastly different. Chambers faced tottenham and Palace in his first two games, and yes, he didn’t have the greatest game against spurs, but he hardly played himself out of the team.The loan move was meant to thrust him into the team and see how he fares in a whole season, but he is riding the bench right now, and not progressing.Would he have played more if he stayed at Arsenal?In my opinion, yes.Shkodran Mustafi has not exactly enamoured himself with his rash decision making and open doors at the back behind him. Chambers is a better bet than the German right now, yet he is currently on the bench elsewhere in London.Alas, he is out of reach and we must hope that Mustafi finds the form that saw him as a fixture of the Germany squads in the last four years. Chambers meanwhile, has a fight on his hands.He will be duking it out with new signing Alfie Mawson at Fulham to play in the first team. If he wins the battle, he could come back to Arsenal an even better player than before.If he consistently finds himself out of favour, he could return to Arsenal with rustiness that takes a while to repair, time that would see his teammates get the edge over him for the next season.
