Paul Pogba may be a doubt for Manchester United’s friendly with Kristiansund when missing coaching on a weekday morning with a back downside, ESPN reports.
The midfielder, who has been linked with moves to Real Madrid and Juventus, sat out the light session at the Ullevaal Stadion just hours before kickoff against Kristiansund in Oslo.
He is rated as 50-50 to be passed fit to face the Norwegian side.
Manager Ole Gunnar Solskjaer is already without striker Romelu Lukaku and defender Matteo Darmian after both failed to make the trip to Norway.
Lukaku, who is wanted by Inter Milan, is yet to feature in the preseason after picking up an ankle injury during the tour of Australia and the Far East.
Darmian also missed the 2-1 win over Tottenham in Shanghai through injury.
Both Pogba and Lukaku are keen to leave Old Trafford before the transfer deadline.
