Jose Mourinho humiliated his former club Manchester United as Tottenham Hotspur swept to a stunning 6-1 win at Old Trafford on Sunday.
Spurs manager Mourinho was sacked by United in 2018 after a turbulent reign, but it was his successor Ole Gunnar Solskjaer who was left red faced after a shambolic display from the hosts.
Uruguayan striker Edison Cavani is reportedly set to join the Red Devils, but it is at the other end of the field Solskjaer's men are in desperate need of reinforcements.
Despite taking the lead through Bruno Fernandes' second minute penalty, United collapsed as they conceded four goals in the first half of a league match for the first time since 1957.
Tanguy Ndombele equalised in the fourth minute after dismal defending from Harry Maguire and South Korea forward Son Heung-min made it two from Harry Kane's seventh minute quick free-kick.
United were reduced to 10 men when Anthony Martial was harshly sent off in the 28th minute for his reaction to a push from Erik Lamela.
That opened the floodgates as United surrendered, with Kane grabbing Tottenham's third in the 31st minute after stealing Eric Bailly's weak pass.
United were in disarray and Serge Aurier crossed for Son's close-range finish in the 37th minute.
Aurier drilled home in the 51st minute and Kane made it six with a 79th minute penalty.
Kane, speaking to Sky Sports, said: "Obviously we got off to the worst possible start but we felt good before the game and in the warm up.
“We had to take our chances and getting the third and fourth really killed the game and then it was about staying focussed.
"We felt really good before the game. The way we reacted after the start showed the mindset we are in.
"We are taking advantage of being more ruthless when the chances come.
"You never want to go behind early but if you react you can switch the momentum. You have to be up for the big games and be ruthless in both boxes. After that first minute they didn't cause any problems.
"When you play so many games it is difficult but there is competition for places and togetherness. It is the one last push before the break.
"I just want to keep going. As the season go by, score as many as I can. Hopefully a few more before the end."
On whether the red card made much of a difference to the scoreline, Kane added: "I think we were on top of the game by then, we had a foothold on it. The fact we took our chances really killed the game."
As for manager Mourinho, he said: “It is history for Tottenham, history for my boys and I cannot deny it is also history for me.
“We were the best team. They couldn’t stop us when we were 11 v 11. We were winning already, we were missing chances. The performance was very, very impressive."
It was just the third time United had conceded six goals in the Premier League era started in 1992.
Solskjaer's team have lost their first two home games for the first time since 1986 and sit just two places above the relegation zone after their heaviest home defeat since Manchester City beat them 6-1 in 2011.
Tottenham are up to fifth place after their second league win this term, ending a run of four games in eight days that included knocking Chelsea, another of Mourinho's old clubs, out of the League Cup on Tuesday.
United defender Luke Shaw called the performance "embarrassing" and admitted the squad need to regroup during the international break.
"We need to look in the mirror, we are nowhere near it at the moment," he said. "Maybe it's lucky that we've got a break now.
"When we went down to 10 men maybe we gave up, there wasn't that character on the pitch. We were too quiet and naive. There was many mistakes, we need to do more.
"It's embarrassing. I was embarrassed on the pitch. We need a long hard look at ourselves."
