Manchester United's forwards have their "mojo" back after leading Tuesday's remarkable 9-0 demolition of nine-man Southampton at Old Trafford.

It was only the third instance of a team winning a Premier League match by nine goals and the first time United have won by that margin since March 1995, when they beat Ipswich Town by the same score.

While Andy Cole was the five-goal inspiration in that 1995 win, this time United shared the goals around – seven players netted on Tuesday, making it only the second occasion so many different individuals have netted for the same team in a single Premier League match.

Among them were Marcus Rashford, Anthony Martial and Edinson Cavani, providing the perfect response to Solskjaer's pre-match comments maligning the loss of his forwards' "mojo".

"Yeah, of course they have," Solskjaer said with a laugh to BT Sport when asked if they had recovered that "mojo".

"You get lots of confidence from a performance like this and the result, scoring goals is always good for forwards and the team."

He added: "We have been waiting for them to show their magic and tonight was a night they could go and enjoy.

"We haven't had too many of those where you can sit down in the second half and enjoy the football, so they enjoyed it. There were some good performances."

Alexandre Jankewitz's red card for a shocking second-minute tackle on Scott McTominay – who was also among the scorers – left Saints with an uphill battle, and Jan Bednarek followed him down the tunnel in the second half in rather more controversial circumstances.

But the focus will be on United's scoring prowess in the contest, as they put Saints to the sword.

Rashford's goal saw him move on to 83 for the club, overtaking Eric Cantona, and Solskjaer took the moment to praise the England international as he has occasionally had to contend with critics urging him to concentrate on his football amid his charitable efforts during the coronavirus pandemic.

"That's not bad," Solskjaer said of Rashford surpassing Cantona. "Eric was a fantastic player to play with and Marcus has a great career ahead of him.

"What he's done this season, this year, it just shows he can still focus on his football as well."

Ole Gunnar Solskjaer believes Manchester United's dressing room is being "driven to success" by Bruno Fernandes, Edinson Cavani and Paul Pogba.

United sit top of the Premier League table on 40 points, six clear of defending champions Liverpool, who Solskjaer's team face in the FA Cup fourth round on Sunday, seven days on from a 0-0 draw at Anfield.

Liverpool have been eliminated from the FA Cup by United more than they have any other opponent in the competition's history, though the Red Devils have lost two of their past three against the Reds in the competition.

Integral to United's recent success has been the form of Fernandes, who has scored 19 league goals and created a further 14 from 33 top-flight appearances since joining from Sporting CP last year.

Veteran campaigner Cavani, meanwhile, has netted five times in all competitions since arriving as a free agent in October, while United's club-record signing Pogba has enjoyed a resurgence after a difficult start to the campaign, and scored a superb winner against Fulham last time out.

Buoyed by the performances of Fernandes, Cavani and Pogba, Solskjaer sees his squad having experienced a drastic shift in mentality, comparing the trio's influence to that of his former United team-mates Roy Keane, Gary Neville and Ryan Giggs.

"I think that runs through the squad and that's part of my thinking when you bring players in," Solskjaer told a news conference.

"You don't just bring big talents in, you research their character as much as you can to have the right types.

"Because there are always players who think 'there's a game next week and I'll still get my wages'. That's the mentality we had to get away from.

"I wanted players to come here to push the boundaries, the levels and drive it on from the inside. It can't come just from the outside. With players like Bruno, Edinson and Paul Pogba, I feel I have a dressing room that is driven to success. That makes my job easier – 100 per cent.

"When you talk the talk, you have to walk the walk. We had players here when I played – Roy Keane, Gary Neville, Ryan Giggs – they drove it on.

"When they spoke you knew you had no leg to stand on to ­argue, because you knew that they did it every single day.

"That's what we need from our players. Many of us in the game have been in dressing rooms where people talk – but you think what are you ­talking about? 

"They talk the talk, but don't really walk the walk. But the players we're talking about – Pogba and Cavani and Bruno – they've been there, they know what it takes and they ­demand it off their team-mates."

The omens are good for United ahead of Sunday's encounter with their bitter rivals, who have reached the FA Cup fifth round only once during Jurgen Klopp's tenure.

United are also unbeaten in their past seven home games against Liverpool in all competitions (W3 D4) since a 3-0 loss in March 2014. They last had a longer unbeaten run against the Reds at Old Trafford between 1990 and 2000 (12 games).

Ole Gunnar Solskjaer wants Manchester United to harness the spirit of the 1999 treble-winning side when they face Liverpool in the FA Cup.

Solskjaer will make changes for the tie of the fourth round at Old Trafford on Sunday after a 2-1 win at Fulham on Wednesday, which put United two points clear at the top of the Premier League.

The Red Devils are still in the hunt for three trophies this season and face an out-of-sorts Liverpool side who are smarting from a shock 1-0 home defeat to Burnley on Thursday.

United dramatically beat the Reds 2-1 at the same stage of the FA Cup 22 years ago courtesy of late goals from Dwight Yorke and Solskjaer, then went on to complete a famous treble.

Solskjaer says dumping the Premier League champions out once again could be a big moment in what he hopes will be a glorious season.

"Of course we can transform a few things from that season. We know that there's tight moments, very fine margins. We know in that season we were close to going out against Liverpool," said the United boss.

"Peter Schmeichel saved a penalty from [Arsenal's] Dennis Bergkamp in the semi-final in injury time. Those moments, I think they gave us the mental advantage, especially in the semi-final.

"But against Liverpool as well in that fourth round, when you get that boost of turning 1-0 down to a 2-1 win against a big team it's massive.

"The FA Cup is a run we've got to enjoy as long as it lasts. We got to the semis last year and we're going to make a few changes but we'll put a team out there that I hope can go through."

Victor Lindelof is available to return from a back injury and Solskjaer will rotate his squad just a week after a drab goalless draw between United and Liverpool at Anfield in the top flight.

"Of course the focus is now on the FA Cup," said Solskjaer. "We know it's a difficult tie, I'm not the best on draws, I think they should try to get someone else in if they want an easy draw."

Solskjaer also said forwards Mason Greenwood, Marcus Rashford, Anthony Martial and Edinson Cavani could all feature in the same side at some stage.

He said: "I used to play in a decent team and the gaffer [Alex Ferguson] had four centre-forwards at least to choose from and with the four front men we've got, we have players to choose from who can get us goals in any game, against any opposition.

"I'm very pleased with the ones I've got and we’re working hard to get the relationships with all of them so we can use them in different ways and sometimes maybe all four of them will play."
