Manchester United boss Ole Gunnar Solskjaer admits Luton Town pushed them hard after their 3-0 Carabao Cup win.

Goals from Juan Mata and substitutes Marcus Rashford and Mason Greenwood secured our first win of the season. Mata, on his 200th start for the Reds, opened the scoring from the penalty spot just before half-time, following a foul on Brandon Williams.

Solskjaer said, "Safe and through? It wasn't safe, they made us work hard for it. But that's what we need, we need to get competitive games and minutes into the legs of our players because normally we're in a pre-season after such [a] short training [period] and pre-season games are different, so I was happy with the competitive nature of this game and of course happy to go through because we'll get another chance next midweek to get more match minutes into players."

On their goalscorers, the manager added: “It's great for them to get minutes as well but also goals. I think the first one [scored by Rashford], I like that goal because the ball goes forward and it goes quick. It's not perfect but Mason gets hold of it, leaves it for Marcus and you can see that he's composed in his finishing. And Mason, you see his chance there, he can go inside, he can go outside, he had one other one before when he went with his right, now he went with his left. Of course, it's great for them to get off the mark."
