Ole Gunnar Solskjaer believes Manchester United's poor home form may be down to coronavirus-enforced changes to their preparations for Old Trafford fixtures.
Before lockdown, United would meet at the Lowry Hotel in Salford on the eve of home matches, with team meetings carried out the next morning before the squad travelled to the stadium via coach.
But under current Covid-19 restrictions, players stay in their own homes the night before matches and travel to Old Trafford separately.
Meanwhile, United still travel together the day before away games and stay in a hotel to prepare.
The Red Devils have lost both of their home games this season, while they have won all five of their away ties across all competitions.
And Solskjaer admitted there may be a real problem with the way his side prepares for home games as he previewed Chelsea's trip to Old Trafford.
"We need to look at the way we prepare," said the United boss. "Maybe it’s something I’ve got to deal with.
"The whole lockdown period has made us do things differently at home so we might have to do it in a different way.
Do you agree with Solskjaer's theory on why United's home form is so poor? Have your say here.
"After the lockdown with Covid, we’ve stayed at home, we’ve had different routines coming into games.
"I’ve just got to look at everything, how the players prepare, because it’s been noticeable how well we’ve done away from home."
Manchester United lost their opening Premier League game 3-1 at home to Crystal Palace before Tottenham ran riot at Old Trafford with a 6-1 victory.
But United have won twice on the road in the Carabao Cup - against Luton and Brighton - and have won both of their away games in the league.
And the Red Devils' 100 per cent record away from home remained intact with an impressive 2-1 win at Paris Saint-Germain in the Champions League group stage this week.
