Mount sink or swim, four eye starting roles and striker experiment in Man United's first friendly

It's a quick return to action for Manchester United. The dust barely seems to have settled on last season before they strap on boots, shin pads and a new strip to get back into matches.

United only returned to pre-season training last Monday. Seven days later they have their first friendly, taking on Norweigan outfit Rosenborg in Trondheim with an inexperienced squad.

It's the first game since the FA Cup final win which effectively saved Erik ten Hag's job. He will be joined by a new coaching team including ex-United striker Ruud van Nistelrooy, and while there will be no new players in the squad tonight there are still plenty of things to look out for.

Plenty of the starters in Trondheim will not line up for the Premier League anthem against Fulham next month but some will. Regardless of who is available, Erik ten Hag uses friendlies as building blocks for the new season. Kobbie Mainoo started in United's first friendly against Leeds United in Oslo last year and was playing his way into the starting XI until that luckless injury against Real Madrid.

Only the squad that has travelled to Norway undermines the fixtures status as a 'first team friendly'. Norwegians who have paid to watch United are entitled to demand their money back. Six - at the most - are household names in the 25-man squad.

Aaron Wan-Bissaka, Casemiro, Mason Mount and Marcus Rashford are the senior players available to start. Harry Amass and Toby Collyer are two academy products Ten Hag has taken a shine to and should get a look-in this week.

Realistically, only Mount and Rashford are vying for starting roles against Fulham.

Amass and Collyer were on the bench 15 times between them last season but did not get on for the first team. That could change
