Chilean import Angelo Henriquez netted his second goal for the club as United's Reserves defeated Stockport County 2-1 in the Manchester Senior Cup.
Following a disappointing first half, the Reds scored twice in quick succession after the interval through teenager Henriquez and Bebe to set up a hard-fought victory against the Conference outfit.

Macheda and Henriquez, on the hour mark, also had decent efforts but a third goal was not forthcoming.
The Hatters made a fight of it by pulling a goal back eight minutes from time when Eckersley headed
