Arsenal striker Joel Campbell is backing Hector Bellerin to prove himself among the best fullbacks in the world.

Such has been Bellerin's form Mathieu Debuchy, signed for an eight figure sum from Newcastle in 2014, forced to leave on-loan for Bordeaux.

“We speak the same language, so it is much easier to communicate with each other," Campbell told the club website.

“We enjoy a very good relationship on and off the pitch. That helps us a lot when we are playing, by speaking with each other, helping each other and giving indications to give our best to the team.

“He is enjoying a very high level, but I think he can give even more. He has the potential to be one of the best in the world.

“He is showing that now, but he is still very young and he has a long way ahead. So I think the best of Hector is yet to come, we haven't seen it yet."
