The Portuguese international and the West Ham loanee were good friends in Istanbul.
West Ham's Gokhan Tore
The Hammers moved to bring in the Turkish international on loan from Slaven Bilic’s former club with a view to a permanent transfer.

It was a deal that caused considerable excitement at West Ham considering the talent he possesses. So far he has struggled to deliver what he is capable of and has struggled to adapt to life in the Premier League.
There have been murmurings that his time at West Ham will be short-lived for some time now and his Instagram post will only exacerbate such rumours.
He posted this message to former team-mate and Portugal international winger Ricardo Quaresma, stating:
There is no doubt that Tore is missing life in Turkey, but it seems he is all set to fight for his place and reputation in English football.

Much like fellow newbies Simone Zaza, Sofiane Feghouli and Jonathan Calleri it has been a struggle for him at the London Stadium so far.
But a good run of form would see him quickly win over the West Ham fans.
