Estudiantes Tecos winger Jürgen Damm has found himself in a contract row with club management.

Damm spent a fortnight trialling with Manchester United earlier this year and has hopes of fielding an offer from the Premier League champions-elect.

However, informador.com.mx says he's been left out of the first team in recent weeks after pressure from representatives on the club for him to play from start.

Agents acting for Damm want Tecos to showcase Damm as much as possible ahead of the summer market, which has upset the coaching staff.
