Fenerbahce have rejected an offer of EUR20million for winger Nani from an unnamed Chinese Super League (CSL) club, according to chairman Aziz Yildirim.
Nani moved to the Turkish Super Lig side from Manchester United in the close-season, having spent the previous campaign on loan at Sporting Lisbon where he started his career.
Fener have now claimed that Nani is the subject of interest from China, with clubs in the CSL spending big so far in January in a bid to raise the profile of the league.
Ramires left Chelsea to join Jiangsu Suning, while Gervinho and Fredy Guarin departed Roma and Inter to join Hebei China Fortune and Shanghai Shenhua respectively in big-money moves.
Yildirim claims Portugal winger Nani has been offered vast sums to follow suit, but insists neither Fener nor the player have any intention of cashing in.
"We've received an offer initially of EUR17m for Nani from a Chinese club. Yesterday they raised their offer to EUR20m," Yildirim said at a council board meeting.
"If we were disposed to sell Nani, they would offer EUR25m. But we rejected this and told our player that we don't want to sell him.
"The club offered Nani EUR10m per year but he also didn't want to leave and told us: 'I want to win the league title here. If I want to leave we talk again at the end of season'.
"I thank him for his manner."
