Ole Gunnar Solskjaer has suggested Old Trafford's red seats could be behind Manchester United's poor home form this season.

The Red Devils fared better on the road, having accumulated 36 points compared 27 when playing at Old Trafford.

And speaking ahead of Thursday's quarter-final second leg with Granada in the Europa League, Solskjaer suggested the form may have had something to do with the red seats in the stadium.

"You'll see a change now, if you see the banners around the club, it's not red anymore," Solskjaer replied.

"We've looked into this, there shouldn't be a reason, really. But some of the payers have mentioned that split-second decision you have to make where you look over your shoulder to see if your team-mate is there or not and the red shirt is on a red background with red seats. So, we've tried to change that along with the anti-racism campaign, that was important that it wasn't red anymore.

"There shouldn't be any reason but, then again, if you have a 4-0 advantage [against Real Sociedad] you don't really have to win that game, 0-0 was a good result, then the first game against Milan, we conceded in the last minute.

"I still think we've played some good football at home. We started off badly with three defeats with Palace, Tottenham and Arsenal very early on, but we've improved."
