Manchester United completed yet another comeback to beat West Ham 3-1 on Saturday, while Chelsea moved top of the Premier League by the same scoreline over Leeds as fans returned to London stadia.
AllNews understands that United fell behind at the London Stadium, but for the fifth consecutive away league game came back to win as a three-goal blitz from Paul Pogba, Mason Greenwood and Marcus Rashford turned the tables in a 13-minute spell after halftime.
United, who have won nine successive league games on the road, are now fourth in the table, one point ahead of Manchester City, who earlier cruised past Fulham 2-0.
Ole Gunnar Solskjaer started with Bruno Fernandes and Rashford on the bench in an attempt to keep two of his star men fresh for Tuesday's crucial Champions League trip to RB Leipzig.
But they were needed to inspire a second-half turnaround after Tomas Soucek's goal seven minutes before halftime gave West Ham a deserved lead at the break.
It seemed like Jose Mourinho, David Moyes would get the better of his former employers, especially with fans in the London stadium.
Cheered on by 2,000 fans in their cavernous 60,000-seat stadium, the Hammers should have been further ahead but squandered their chances.
Pogba started the fightback in the 65th minute with a superb strike from distance and minutes later United were ahead, Greenwood turning and firing home in the area.
Rashford struck a post as United looked to extend their lead, and it was the England striker who made it 3-1 12 minutes from time.
"When you are 1-0, 2-0 down the boys still believe and that character is important," said Solskjaer. "At the end of the season, you don't care about the performance."
CHELSEA TOPS ENGLISH SUMMIT, LEEDS DROPS
Chelsea also came from a goal down to win 3-1 as fans made a return to Stamford Bridge for the first time since March.
"It was nice to feel their support," said Chelsea boss Frank Lampard. "2,000 doesn't sound like a lot, but the noise they can generate was incredible. It's a tentative step but pleased to have them back."
Patrick Bamford gave Leeds a shock early lead as he took advantage of hesitation in the Chelsea defense to round Edouard Mendy and slot home his eighth goal of the season.
However, Lampard's men are now unbeaten in 16 matches in all competitions and showed why they are serious title contenders by storming back to win comfortably.
Timo Werner denied Giroud a quick response by clearing his strike partner's goalbound header onto the crossbar.
However, Giroud, who earned a rare Premier League start after scoring four against Sevilla in the Champions League on Wednesday, leveled on 27 minutes from Reece James' low cross.
Illan Meslier in the Leeds goal ensured Werner continued to have a frustrating night in front of the goal, but Chelsea finally made their chances count when Kurt Zouma headed home Mason Mount's corner.
And in stoppage time, Werner turned provider for Christian Pulisic who subbed in for injured Hakim Ziyech to secure all three points.
