Estudiantes Tecos have offered more detail of Jurgen Damm's trial with Manchester United.
The Mexicans say he is returning to the club after his trial at United:
"Our player was invited to be observed directly by Manchester United of the Premier League. The forward traveled to England on 20 January to begin a period of observation under the club's coaching staff, as they have two ways to integrate new players into the club and one of those is direct examination by staff in their own facilities.
"Damm will return to our city next weekend and will be back in the Estudiantes Tecos side on 4 February to continue his participation in the 2013 Clausura."
