As Alex Ferguson once said: "Football, bloody hell". On the day Old Trafford paid tribute to Ferguson's late wife Cathy, Manchester United pulled off the type of epic comeback they became famous for under the legendary Scottish manager.
And this time the hero was a Scotland international: Scott McTominay. The midfielder had only come off the bench in the 87th minute and his entrance looked like a desperate move from Erik ten Hag, who was on the verge of becoming the first manager to lose three games in a row at Old Trafford since Matt Busby in 1962.
But it proved an inspired change as McTominay pulled United level in the 92nd minute then headed home a Harry Maguire cross in the 96th minute, sending a disbelieving Old Trafford wild.
The win was all the harder to digest as United had played so poorly. They had given away a soft goal by Mathias Jensen after sloppy giveaway from Casemiro and a botched clearance by Victor Lindelof. Even leaving aside that poor goal, they had looked utterly void of belief and inspiration.
But McTominay, a boy made in United's academy, saved the day. And he may have saved Ten Hag's job as well.
