United's Reserves retained the Manchester Senior Cup after Zoran Tosic's early goal proved enough to overcome Bolton Wanderers at the Reebok Stadium.
The Serbian struck his first Reds goal since arriving in January after eight minutes, as his heavily deflected free-kick wrong-footed Trotters goalkeeper Adam Bogdan.
United peppered the hosts' goal with shots on goal, with only inspired goalkeeping from Bogdan keeping the difference down to a single goal. That precarious advantage meant Bolton were always in the tie, however, and Ben Amos was required to make two fine saves himself midway through the second period.
The Reds' intent to attack was signalled by a line-up which contained Kiko Macheda, Danny Welbeck, Lee Martin and Tosic as Ole Gunnar Solskjaer and Warren Joyce sought to secure the second trophy of their spell in charge.
The early exchanges belonged to United, who immediately put the hosts under pressure. When Tosic struck from 20 yards, albeit via a sizeable deflection off the wall, it had been coming. Two minutes later, Macheda headed Martin's free-kick over from six yards.
From there, Bogdan took centre stage. First he superbly finger-tipped a low Tosic effort wide, then fielded a powerful close-range effort from Martin before Macheda and Eckersley both fired narrowly off target.
Martin seemed to have doubled United's advantage on 35 minutes as he raced onto Macheda's pass and slotted through Bogdan's legs, only for a late and slightly harsh offside flag to keep the scoreline intact.
Another deflected Tosic effort dribbled just wide the post as United ended the first half on top, and the game continued in the same vein after the break as Bolton struggled to cope with the Reds' passing and ball retention.
Tosic twice drew solid saves from Bogdan as a second goal seemed inevitable, but Bolton served belated notice of their threat in drawing two superb saves from Reds goalkeeper Amos around the hour mark.
