Former Manchester United midfielder Owen Hargreaves has pinpointed a potential banana skin that could cost the Red Devils the chance to become Premier League champions.
Ole Gunnar Solskjaer’s men suffered an embarrassing 2-1 loss to bottom club Sheffield United on Wednesday.
United have not kept a home clean sheet in the league since their 1-0 victory over Wolves on December 29.
Cross-city rivals Manchester City thumped West Brom 5-0 earlier in the week.
They have conceded just 13 times all season and currently sit in top spot.
This, Hargreaves said, is something that the Old Trafford outfit should be concerned about.
“I think the biggest worry is that Manchester City are playing as well as they are,” he told Premier League Productions (via the Metro).
“The fact that they don’t concede. They absolutely blew West Bromwich Albion away without even playing a centre-forward at the moment and winning 5-0.”
Pep Guardiola’s side have now gone four league games without shipping a single goal.
Hargreaves went on to highlight how they once again look offensively clinical too, unlike United.
“The bigger worry is that Manchester City look like they’ve found another gear,” he added.
“There was a moment when we were saying: ‘They’re not scoring, they’re not creating’ but yesterday (Tuesday) they could have won 10-0.
“I think for United they’re not looking like scoring and having defensive issues, Ole alluded to it.
“Not being in position and not getting out to the ball that’s a bit of a worry because defensively and offensively they have been really good. City are making steps forward and finding their form.”
United dressing room shaken
The shock defeat to the Blades meant United missed the chance to leapfrog City and move the top of the league.
Captain Harry Maguire revealed what the home dressing room was like following the loss to the Blades.
“The boys are devastated in there, if I’m being honest,” he admitted. “It’s a really quiet dressing room. The boys are so disappointed.
“When you do get a defeat, there’s nothing worse than waiting time to get back out on the pitch to play and put things right.”
United travel to the Emirates to take on Arsenal on Saturday in their next league fixture.
