Turkey international Bolat is currently training with Fulham ahead of a proposed January switch.
The 24-year-old is out-of-contract in the summer and it is believed a deal between Standard and Fulham has already been agreed.
However, Bolat is yet to agree personal terms with Fulham - but that is not expected to be an issue.
"With Sinan himself, there is no agreement, but I don't suppose he will say no," confirmed Standard's technical director Jean-Francois de Sart.
There is little rush for the deal to be completed in earlier January as he is currently recovering from a serious knee injury which saw him miss most of last season.
