Bundesliga club Schalke 04 have tabled a €7 million bid for Ghana forward Bernard Tekpetey.
The 21-year-old left the Veltins-Arena side in the summer to join SC Paderborn 07 for € 400,000.
Tekpetey put up an excellent performance which helped secure top flight league promotion for SC Paderborn 07.
Schalke 04 are aiming to re-sign him to bolster their squad after they inserted a buy-back clause in his contract.
The Veltins-Arena club have endured a poor season finishing 14th on the League table.
Tekpetey played 32 games, scoring 10 and assisting four times for SC Paderborn 07 to secure promotion in the Bundesliga.
