Martial and Rashford - who netted for the first time since the resumption - both have 20 goals for the season and, together with Greenwood's contribution of 15, they have now scored four more than champions Liverpool's much-vaunted front three of Mohamed Salah, Sadio Mane and Roberto Firmino in 2019-20.
This was the first time Manchester United scored five or more goals in a home league match since 26 December 2011, when they beat Wigan Athletic 5-0.
Rashford, who scored his 20th goal of the season in all competitions and the first since the league resumed on June 17 following a three-month break due to the coronavirus pandemic, was delighted.
Solskjaer still needs to do a lot of patchwork to his first-team squad but with the way the OT outfit have been playing not only do they have the chance of finishing in the top-four but they might also end the season by winning a few silverwares. "It is a big bonus to have him in the squad".
Solskjaer was thrilled with the win, saying: "That is a game for the fans".
With Fernandes also setting up two goals, the Portugal playmaker has six goals and five assists in nine league games since moving from Sporting Lisbon in January.
A Mason Greenwood brace and another impressive performance from Bruno Fernandes meant that the Red Devils have not lost for 16 straight games in all competitions, with 12 wins in the process. During that time, they've managed to get on the scoresheet in 15 matches, only failing to do so in a 0-0 draw against Wolves in February.
"If he shoots he will score, he is going to get better and his general play has improved".
United have found it tough relative to their lofty ambitions since the departure of Sir Alex Ferguson in 2013 but on Saturday, Solskjaer will have been proud to see his side roll back the years as if the Scot were still in the dugout.
