Solskjaer didn’t have to wait more than 180 seconds for his first goal as United boss, as Rashford scored a pinpoint free kick around the wall and inside the far post.
Calum Paterson and Luke Shaw knocked heads in the 13th minute, stopping play so both players could receive treatment.
Herrera and a wicked deflection combined to provide an aesthetically pleasing goal in the 29th, as Paul Pogba set up the Spaniard for a shot that knuckled into the goal after turning off Greg Cunningham.
Cardiff re-entered the game when Rashford was judged to have handled the ball in the box, and Camarasa finished his chance from the spot and it was 2-1 in the 38th.
Martial barely required more than a couple of minutes to make it 3-1, working one-touch passing with Pogba and Jesse Lingard before beating Neil Etheridge.

Lingard won a penalty with a dribble through traffic, as Sol Bamba appeared the likeliest to have taken down the United man with a tug on the arm. He converted his own chance to make it 4-1.

Kenneth Zohore couldn’t sneak a shot past De Gea, winning a corner in the 77th minute.
