The son of West Ham chairman David Sullivan has revealed that Gokhan Tore has joined the club after a “very big” loan fee was agreed with Besiktas.

Jack Sullivan, who is a reliable source of Hammers news, claimed the deal to secure the winger was now finalised.

Website Turkish Football claimed that the Londoners have agreed to sign the star winger in a £13.5million transfer package which includes a £11million loan-to-buy option and £2.5million loan fee with Besiktas.

Football Insider reported on Sunday that Tore had completed a medical with the east London outfit ahead of his summer move to the club.

Sullivan junior did not divulge precise figure but gave some insight to his 68,000 Twitter followers.

“Tore done, loan with option to buy!! Very big loan fee,” he said on his personal Twitter account.

The Turkey international has been a long-term target for West ham, with manager Slaven Bilic having worked with him when they were together at Besiktas.

Tore has had a steady season, scoring six goals and providing nine assists in 35 appearances in 2015-16.

The former Rubin Kazan star will become the club’s fifth signing following the arrivals of Sofiane Feghouli, Toni Martinez, Havard Nordtveit and Domingos Quina.
