Robin van Persie's move to Fenerbahce was confirmed earlier this week after three seasons and one league title at Manchester United, however the clubs have been unable to agree a fee for the Dutch striker.
According to ITV, the two clubs have been haggling over figure within the region of £5 million, but as of yet no fee has been confirmed.
This news did not appear to be a problem for United who were happy to allow their former striker to complete his move to Turkey before all the formalities were completed.

The forward, who scored 48 goals in 86 league appearances for the Red Devils, spoke of his delight at joining the club following 12 years in England.
The 31-year-old is the second Manchester United player to join Fenerbahce this summer along with Nani.
It is not expected United will receive a big fee for the striker, who turns 32 in three weeks, despite spending £24 million to bring him to Old Trafford in 2012.
The goals of Van Persie will live long in the memory of many United fans as he fired home 26 goals in his debut season to help wrestle the title back from their "noisy neighbours" Manchester City.
Following the retirement of Sir Alex Ferguson, Van Persie could never recapture his form and even the introduction of former Holland manager Louis van Gaal, who used Van Persie to devastating effect in the World Cup, failed to reignite the flame.
With the Dutch striker and Columbian forward Radamel Falcao no longer at Old Trafford, Louis van Gaal will be looking for further additions to lead the line for his new look side next season.
PSG's Uruguayan forward Edinson Cavani is a name that has been thrown around in recent weeks and a deal between the two clubs that could see Angel di Maria head to Paris.
Other possibilities include Bayern Munich forward Robert Lewandowski, but it would take a serious outlay of cash for the Red Devils to snatch another player from Bavaria.
Christian Benteke is also in contention but Aston Villa's asking price of £32.5 million seems to be putting off potential suitors for the Belgian international.
United's signings so far this summer have created an air of excitement around the club, with many tipping them to challenge for the title, but with only two recognised strikers in Wayne Rooney and James Wilson, the final third of the pitch is a major concern for the Red Devils.
