Victor Lindelof's international boss Janne Andersson has voiced serious concerns over the Manchester United player's fitness amid the current strenuous schedule.

The Sweden manager believes the current international and domestic fixture lists are “total insanity” and is worried about the back injury that United defender Lindelof is carrying at the moment.

Lindelof started Sweden's UEFA Nations League games against Croatia and France over the international break and returned to play the full 90 minutes in United's 1-0 win over West Brom on Saturday night. That was despite Ole Gunnar Solskjaer admitting the 26-year-old's back was "not great".

Andersson told Fotbollskanalen that he hopes Lindelof gets the chance to rest and recover amid concerns over his back. The centre-back remains integral for both club and country.

“He basically plays Sunday, Wednesday, Saturday, Tuesday and so on, for as long as he wants," said the Swedish boss. "And he had hardly any leave at all between the seasons now.

“That not more players have injuries… I am surprised. I am also surprised that there has not been more discussion and reasoning about it from a sporting and medical perspective. This is extremely tough for the players. And it’s not like they play against bad teams. These are very tough matches all the time.

Manchester United ground out a 1-0 win over West Brom to finally notch a victory at home in the Premier League this season.

It wasn't pretty but it means two successive wins for Ole Gunnar Solskjaer's side, who have to balance league and Champions League commitments over a busy period in the coming weeeks.

“I really hope Victor can get his back in order. Injured players… it’s not fun. If he gets the chance to fully recover, we will see in the future.”

United host Istanbul Basaksehir in the Champions League on Tuesday night and Solskjaer could opt to rest Lindelof in favour of Axel Tuanzebe. The United boss himself has been outspoken about the schedule and how it takes its toll on players after Luke Shaw was injured against Everton before the international break.
