Fenerbahce have stepped up efforts to sign Sunderland winger Jeremain Lens on a permanent deal.

The Netherlands international is currently on loan at Fenerbahce after joining on a temporary move over the summer but the Istanbul giants are keen on extending his stay.

A source close to the club revealed to Turkish-football that Fenerbahce are in talks with Sunderland over signing Lens on a permanent deal however, have been unable to agree to a transfer fee.

Fotomac meanwhile, claim that Fenerbahce aim to find a way around the transfer fee issue by offering Nigerian international Emmanuel Emenike as well as Netherlands international Gregory van der Wiel on a part-exchange deal.

Emenike does have Premier League experience having previously played on loan for West Ham and he has been in decent form for the Yellow Canaries scoring seven times and providing four assists in 20 games.

Van der Wiel meanwhile has struggled for playing time since making his move from PSG but he is represented by super agent Mino Raiola who has close ties in most major leagues across Europe.

Lens has hit the ground running at Fenerbahce establishing as a candidate for player of the season – for the first half of the campaign anyway.

The explosive winger has three goals and providing eight assists in all competitions for Fenerbahce who have booked a place in the Europa League Round of 32.
