Former Cameroon coach Claude le Roy has hailed the impact of Inter Milan goalkeeper Andre Onana.

Le Roy says Onana will be key to a successful World Cup.

The Cameroon international joined Inter from Ajax over the summer.

“When we won the African Cup of Nations in 1988 with Cameroon, it was because we had Joseph-Antoine Bell who was a top-class goalkeeper," he said.

“And since Senegal, Cameroon and Morocco, have very good specialists in this position, they can have high ambitions."
