Flashback to Ole Gunnar Solskjaer scoring four goals 20 years ago today

Ole Gunnar Solskjaer is working tirelessly to restore the attacking ethos that was the hallmark of Sir Alex Ferguson's great Manchester United sides.

And there are few greater examples of that philosophy than the masterclass Solskjaer himself produced at Nottingham Forest 20 years ago today.

United were leading 4-1 when the Norwegian striker came off the bench at the City Ground with 18 minutes of the Premier League fixture remaining.

Dwight Yorke, whom he replaced, and Andrew Cole had scored two goals apiece that afternoon but Solskjaer would eclipse them both by scoring four times in just over 10 minutes.

The Premier League tweeted out highlights of United's 8-1 win - which remains the biggest away win in the competition's history - and fans were quick to reminisce.

One wrote: 'Lol he was so casual at treating a Premier League team like a group of seven year olds in the park.'

Another replied: 'From Nottingham and the joke going around school the day after this match was 'Forest fan bought eight pies on the way home, but he was so sad he only 8-1!'

One recalled: 'Love how after this game Ron Atkinson [the Forest manager] said that Nottingham Forest had just been in a 9 goal thriller.'

That afternoon on the banks of the River Trent was when United's ultimately glorious Treble campaign really caught fire.

Ferguson's side had been engaged in a cat and mouse title chase with Arsene Wenger's Arsenal for months and had proved remarkable tough to beat.

A week before the annihilation of Forest, United had won at Charlton thanks to a last-minute Yorke winner - something that would become their forte - and midweek had seen a scraped 1-0 win over Derby.

But United were in full flow against Forest, taking just two minutes to take the lead when Yorke turned home a right-wing cross from Paul Scholes.

Forest actually equalised five minutes later through Alan Rogers but that proved the only negative in United's afternoon.

Cole restored their lead less than a minute later, skipping around Forest keeper Dave Beasant before scoring from a narrow angle.

And United were home and dry against the relegation strugglers when Cole and then Yorke added goals after half-time.

Given their ruthless streaks, no doubt Cole and Yorke were both eying hat-tricks at that point but Yorke was taken off for Solskjaer, who trumped them both.

With 10 minutes left on the clock, he side-footed home from two yards after Gary Neville had played a cross through the six-yard box.

Solskjaer then beat the offside trap to gather David Beckham's pass, seeing his attempted lob blocked by Beasant before pinging the rebound into the top corner.

The ball sat up nicely for Solskjaer to rattle in his hat-trick goal in stoppage time, taking United to seven goals.

And when Scholes mis-hit a Nicky Butt cross in the muddy penalty box, Solskjaer was on hand to sweep home his fourth and United's eighth at the death.

Remarkably, there were only 10 shots on target in the match by both sides - with nine finding the net for a conversion rate of 90 per cent.

United were unstoppable from then on, remaining unbeaten in the league to pip Arsenal by just one point after a dramatic final day win over Tottenham.

Ferguson's side also won the FA Cup, defeating Newcastle 2-0 in the Wembley final, and the Champions League, where Solskjaer's stoppage time goal defeated Bayern Munich in one of the most dramatic finales to any final ever.

How Solskjaer will wish for something similar now he is in charge at Old Trafford.
