The value of the offer remains undisclosed, but the German giants are hoping it will be enough to tempt the Potters into a sale. Tuncay has struggled to hold down a regular first-team place at the Britannia Stadium - although he has enjoyed a recent run in the side - but the Turkey international has always maintained he is happy at the club. Tony Pulis has also insisted the 29-year-old has a part to play at Stoke but speculation has rarely gone away that a transfer may be in the offing. Sunderland and West Ham have been linked with moves, but an official approach has now been made from Germany, according to German newspaper Bild. It remains to be seen whether Pulis will agree to let Tuncay leave - Ricardo Fuller could be on the move - but Wolfsburg are desperate to bolster their attacking options and could make the Potters an offer too good to refuse. Schalke are currently languishing in the bottom half of the Bundesliga table but are also understood to have made a move for Schalke's Jefferson Farfan as they seek to arrest their slump.
