The United bus took more than an hour to travel half a mile.
Manchester United boss Jose Mourinho disguised himself under a hoodie as he walked to the ground for the Champions League clash with Juventus as traffic problems again affected Old Trafford on a European night.
The club were fined 15,000 euros (£13,244) after their last Champions League match against Valencia kicked off late.
The Juventus bus made it to the ground just before 7pm for the 8pm kick-off, with the United bus arriving around 15 minutes later having taken more than an hour to travel half a mile. No delay to the kick-off was necessary this time.
United stayed at the Hilton hotel at the nearby cricket ground, but Mourinho decided to walk to Old Trafford, accompanied by one security guard, instead of travelling with his players.
He told BT Sport: “We changed hotel, the hotel is just around in the corner.
“The players are in the bus for 45 minutes. I walked with a hoodie in the middle of the fans, nobody recognised me. I took two minutes, what I took two minutes walking the players couldn’t do 45 minutes in the bus.
“Juventus are having the same kind of problem. I informed the UEFA delegate about the situation because we don’t want to be punished again.”
