Manchester United’s demoralising defeat against Manchester City in their League Cup semi-final laid bare their desperate need for reinforcements if they are to salvage anything from their stuttering season.

United conceded three first-half goals in a match at Old Trafford for the first time since May 1997 on Tuesday in their chastening 3-1 first-leg loss against Pep Guardiola’s men.

Manchester United manager Ole Gunnar Solskjaer has a huge task on his hands to turn around the club’s fortunes

Bernardo Silva’s wonder strike, Riyad Mahrez’s cool finish and an own goal from Andreas Pereira put City well on course for a third straight final before Marcus Rashford gave the hosts faint hope for the second leg on January 29.

The defeat was another stark reminder that United are light years behind the standards set by Premier League pacesetters Liverpool and defending champions City.

Manager Ole Gunnar Solskjaer said there would be no easy solutions as United attempt to claw their way back to the top of English football.

“I’ve said before it is not going to be a quick fix and the two teams you are talking about are probably two of the best teams in the world,” he said.
