West Ham have confirmed their injured forward Andre Ayew has been receiving specialist treatment at former club Marseille.

The Hammers say it's too early to put a time frame on his return to first team action, but he won't need an operation and a ball will soon be introduced to his rehabilitation sessions.

The decision to let Ayew travel to France for treatment was made so that he could be closer to home while Marseille, where he has been spending 25 per cent of his time, also have equipment to benefit his recovery.
