The report quotes Bilic as saying: “Kerim Frei already has Premier League experience he is a player just about every manager could do with.”
Bilic does of course know Frei well from his two-seasons in charge of Besiktas and gave the young winger playing time under his stewardship.
West ham could face competition for Frie from West Brom who are plotting a move for the Beşiktaş winger according to the Mirror.
The 22-year-old is of no stranger to top-flight football in England having rose through the ranks of the Fulham academy before his move to Besiktas two years ago.
The Turkish international winger started to break into the Besiktas first team team last season scoring five times and providing another five assists in all competitions for the Turkish champions.
Frei does have another two-years remaining on his current contract with the Black Eagles and would be expected to play Champions League football next season if he were to say.
