Polish goalkeeper Bartosz Mrozek is trialling with Manchester United.

The Daily Express says United have taken 15-year-old Mrozek on a trial.

The Lech Poznan stopper has travelled from his homeland to Manchester, where he will spend a few days being put through his paces by the United chiefs.

United reportedly made the approach to the goalkeeper in December.

It is believed that United have been watching the goalkeeper for over 12 months now and are keen to tie him up for the long-term should he impress while on loan.
