Manchester United waited 16 years to play rivals Leeds United in the English Premier League and wasted no time making them pay for it.
The hosts charged to a 6-2 victory on Sunday, though both teams could easily have scored more, as the Red Devils roared back in to the title race by moving up to third.

Man United's defensive midfielder Scott McTominay - who hadn't scored in the league since March - netted in the second and third minutes before Bruno Fernandes and Victor Lindelof extended United's, with more goals from Daniel James and Fernandes in the second half.
Up against the all-action style of Leeds coach Marcelo Bielsa, United manager Ole Gunnar Solskjaer credited his team with beating Leeds at their own game.
"We had to earn the right to win it by running just as much or more than them, so that was a challenge against one of the fittest teams in the league," Solskjaer said.
Jamie Vardy's hot form in away games in 2020 continued as he scored in first-half stoppage time with a penalty and then forced an own-goal from Toby Alderweireld in Leicester's win at Spurs.
"We came here with a game plan and we absolutely nailed what we wanted to do...," Vardy told broadcaster Sky Sports.
Sam Allardyce is the coach teams turn to when they need to avoid relegation from the Premier League but he didn't have an immediate effect in his first game with the 19th-place Baggies.
