Gokhan Tore is set to make his official West Ham debut tonight when the Hammers take on NK Domzale in the Europa League.
The Hammers will have to find a way past the Europa League qualification stage to book a place in the group stages.
Tore joined West Ham on a one-year loan over the summer and the East London based outfit have a £10 million release clause.
Tore is no stranger to the Europa League and under the stewardship of Bilic – during his time in charge of Besiktas – the Black Eagles reached the quarter-final stages in 2014 beating Liverpool and Tottenham along the way.
The Turkish international winger was also part of the Besiktas side that made it out of the group stages in the tournament last season.
Tore shared an Instagram photo to his followers in which he appeared to be in high spirits and pretty well settled in by the looks of it.
