Per Mertesacker, Arsenal defender says he sees teammate, Calum Chambers becoming one of the best defenders in the game.
Chambers made the move from Southampton to Arsenal in July of 2014 and has become a regular at Old Trafford.
However, Chambers is yet to become an undisputed starter at the Emirates. Mertesacker sees him heading towards that
“He’s a good guy and we challenge each other every single day in training,” the German defender told Arsenal Player.
“That’s what it’s all about. He’s eager to learn, he really fancies challenging every single centre-back and that’s something you need. When you step up as a young talent, you need to challenge the old lads.
“It’s really good to have him so that we can improve. You never stop working, you never stop doing things because there’s someone behind you – in a respectful way – who is giving absolutely everything in every single training session.
“That’s what my feeling is. When he does that, he’s got a great chance to develop as one of the top centre-backs.”
