According to Sport Bild, Mainz want to extend star striker Karim Onisiwo and left-back Aarón Martín as soon as possible.

Martín has really stepped up at left-back, as his deal expires at the end of the season. Both players have combined for seven goals thus far, but it's currently unclear if the two starters even want to extend.
Mainz sit 6th in the table with 18 points through 11 games and play Bayern on Saturday.
