League One outfit Leeds United have handed a trial to young American striker Mike Grella.
The 21-year-old, who turns 22 on Friday, has represented USA at both Under-18 and Under-20 level.
Grella has been granted permission to play in Leeds' reserve clash against Barnsley on Tuesday.
The striker will partner Malcolm Christie up front under the watchful gaze of manager Simon Grayson.
Grayson has been busy in the winter transfer window, having already brought in Lee Trundle, Richard Naylor and Carl Dickinson on loan.
