William Saliba is being backed for success at Arsenal.
Former St Etienne teammate Harold Moukoudi is confident Saliba has what is needed to succeed in England.
He told Goal: "With the qualities he has, I'm sure he will take the chance when he gets it.
"He has enormous potential and he will succeed, I am sure of that."
Saliba is still waiting to make his competitive debut for the Gunners. Thus far, he has managed just one U23 appearance this season.
