United's Reserves scored a goal in each half to earn a 2-0 success against Wolves with skipper Davide Petrucci and Larnell Cole on the mark.

Cole was not to be denied and made it 2-0 on 66 minutes. Tunnicliffe, playing well in midfield, picked out Will Keane and the forward intelligently fired the ball low across the
