Diafra Sakho's contract with West Ham includes a two-year option that the club can trigger to keep the supposedly unhappy striker at the London Stadium, it can be revealed.

The Senegal international was left frustrated in the summer after missing out on a move to French side Rennes on deadline day.

West Ham are in a strong position with their two-year option on Sakho but could still try to hand him an improved contract if he continues to perform. That was what they did with Michail Antonio, whose fine form last season saw him rewarded with a double-your-money deal.

It remains to be seen whether Sakho, who has scored three goals in his last three games for club and country, will try to leave at the next chance.

Though it was widely reported that his contract expires at the end of this season, Sportsmail can confirm it in fact runs beyond the current campaign.

Meanwhile, manager Slaven Bilic wants West Ham's supporters to cut him some slack by not by booing his decisions but to show trust in him instead.

It comes after a double substitution against Swansea before the international break was met by a chorus of jeers at the London Stadium. To Bilic's credit, it worked.

Javier Hernandez and Andre Ayew were replaced by Sakho and Arthur Masuaku before the two substitutes linked up to secure West Ham a vital 1-0 win.

It was not the first time this season that one of Bilic's calls had led to severe criticism from the crowd and the Croatian has said: 'It's better to be clapped than booed.

'But at the end of the day I have to trust my decisions. Those decisions gave us what we wanted.

'But it doesn't have to be that the next time we will do the same decision. The fans were not happy with my decisions (to take Hernandez and Ayew off) but they were really good.'

Asked whether Hernandez knows he is not exempt from being dropped to the bench, with competition from Andy Carroll and Sakho, Bilic continued: 'Nobody is.

'As a manager a big part of your job is to make decisions. Is it before a game? Is it during training? Are they football decisions or non-football decisions?

'The game decisions are very important ones. They are crucial. In the last game me and my staff took the decision because it was the right decision.'
