Manchester United eased past LA Galaxy in the opening game of their US tour – as new signings Romelu Lukaku and Victor Lindelof made their debuts.

Marcus Rashford scored twice and could have had a first-half hat-trick before he made way for the £75million man to make his debut as Jose Mourinho changed his entire team at the break.

But Lukaku could not get on the scoresheet despite two good second-half chances.

Rashford scored twice in his 45-minute outing, with Marouane Fellaini grabbing United’s second.

United continued where they left off after the break,with Henrikh Mkhitaryan and Anthony Martial also getting on the scoresheet, although Galaxy scored two late consolation goals.

Mourinho experimented with three at the back, a system he used on only four occasions last season, as he began with a 3-5-2 formation in the first half.

“We will play in a system that is new for us and it’s important to see how we cope with it because it’s going to be difficult,” said the United boss before kick-off.

“It is not going to be our main system. We are always a team that normally plays four at the back, but during the season we maybe need to do it.

“Last season we did need to do it against Rostov at home and away, so maybe we need to adapt to some matches and pre-season is exactly for this – especially the second pre-season, which it is now.

‘We are going to try what we have been doing in training in these first few days,” he added.

All in all it was impressive from United in this first match of their US Tour which moves on to Salt Lake City for the Tuesday morning game against Real Salt Lake.
