Arsenal defender Per Merttesacker is supremely confident that Calum Chambers has a bright future ahead.

The 20-year-old joined the Gunners from Southampton in the summer transfer window last year and impressed in his debut campaign for the North London club.

The early-season form of Gabriel Paulista has so far restricted the output of Chambers in 2015/16 but teammate Mertesacker has assured outsiders that the three-time England international will become a quality player for the club in years to come.

"He's a good guy and we challenge each other every single day in training," the vice-captain 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.

"It's a good situation for us because every player gives something to the team," Mertesacker added. "It's not only about taking something or taking a place, for us it means more to play for Arsenal than just getting a spot in the lineup.

"It's a good situation for all of us. There will be small niggles, injuries and sicknesses so we have to find a way of playing with each other, no matter who's playing. That is the situation but it's a very respectful situation."
