Sunderland are waiting for a promised donation to their Charity Foundation from former striker Asamoah Gyan.

The Daily Mail reports the former African footballer of the year, and Sunderland's record signing, was allowed to join UAE club Al-Ain in a £200,000-a-week tax-free deal at the beginning of last season.

As part of the lucrative move, Gyan agreed to make a sizeable donation to the club's own community scheme which has ploughed millions into the region through education and football programmes for the last nine years.

Gyan, whose total earnings in the last year will top £10.4million, has failed to pay the donation, believed to be in the region of £100,000.

A club spokesperson confirmed: "The donation has not been received to date, however we are hopeful that this is merely an oversight on the part of Asamoah and his representatives.

"The Foundation does a tremendous amount of work with young people in the North East region and a donation of this kind will help to fund some fantastic programmes and support youngsters from some of the most vulnerable areas of society."
