A new-look United side looked comfortable without the chances their patient passing style warranted until Wilson notched the first of his two goals after 31 minutes. Marouane Fellaini nodded down a free-kick and Wilson, 18, lashed the ball home from eight yards out, between goalkeeper Eldin Jakupovic’s legs, for an unforgettable start to his United career.
Wilson went close to adding another early in the second half, turning the ball over the bar after good work from Lawrence. A couple of attacking substitutions by Hull manager Steve Bruce opened the game out more in the second half, but it was Adnan Januzaj who went close to scoring when his rasping shot was forced wide by Jakupovic.
United doubled the lead just after the hour when Wilson pounced on a rebound from a Fellaini shot, but Hull hit back straight away when Matty Fryatt bent the ball in around David De Gea from long range with a superb strike.
Giggs replaced the youngsters, bringing on Robin van Persie and then himself, and the player-manager was soon rolling back the years with a couple of incisive runs that worried the Hull defence. De Gea blocked David Meyler’s well-hit strike from distance, and van Persie saw a shot bend wide before the Dutchman made sure with a strike from the edge of the box from a Giggs pass. Jakupovic denied the interim boss a goal with a flying save from a free-kick towards the end.
