Manchester City's Riyad Mahrez says it was only a matter of time before his international team-mate Said Benrahma became a success at West Ham.
The Algerian colleagues will be up against each other in a battle between two of the top four at The Etihad this afternoon.
Benrahma's has become a regular in David Moyes' team and already doubled last season's tally of three goals.
Mahrez, who had his own teething problems following a £60million move from Leicester, had no doubts it would work out for the Hammers playmaker.
