The talented 22-year-old is out of contract in the summer and could follow teammate Leon Goretzka, who recently signed a pre-contract agreement with Bayern Munich, out of the exit door.

Barcelona are also monitoring Meyer's situation, according to the Daily Star, as the Germany international continues to impress in Schalke's quest to attain a Champions League place.

Schalke are still hopeful of extending Meyer's contract, despite their frustrations at already losing Goretzka.
