David Moyes is set to step up his interest in Dutch midfielder Wesley Sneijder by offering Galatasaray both Nani and Antonio Valencia in exchange in January. Reports in Turkey suggest that Manchester United will return for Sneijder in January having missed out with a £6m bid for the 29-year-old over the summer. It is thought that United were willing to offer up to £12m for Sneijder - who has also been linked with Chelsea - in the upcoming transfer window. But it seems that they hope to tempt Galatasaray with players instead of cash. Both Nani and Valencia have been tipped to leave United after failing to win over David Moyes this season. And with former Manchester City boss Roberto Mancini at the helm in Istanbul, both players been linked with a move to Turkey. Galatasaray's new transfer policy sees them trying to become younger and more home-grown but they could make an exception for Nani, 27, and Valencia, 28. However, it seems that United still have some work to do to convince Sneijder to make the move. The former Real Madrid star recently said: "I'm going nowhere, your going to keep seeing me in a red and yellow shirt."
