Chelsea head coach Graham Potter felt a draw was a fair outcome after Casemiro's last-gasp header earned Manchester United a point at Stamford Bridge.
The Brazilian, who had been excellent in the centre of midfield, leapt highest inside the penalty area to connect with Luke Shaw's superb cross to head home a dramatic 94th-minute equaliser, making it 1-1. United had fallen behind with just three minutes of normal time left on the clock via a Jorginho penalty.
The Italian dispatched the ball from 12 yards after substitute Scott McTominay had dragged Armando Broja to the turf at a corner. United, though, refused to roll over, showing the courage and fight needed to earn something from the game.

The Reds were the better side for long periods of the contest, particularly in the first half, forcing Potter into a tactical rethink before half-time. He was forced to pack his side's midfield a little more, bringing on Mateo Kovacic in place of left-back Marc Cucurella.
And although the Chelsea boss, who remains unbeaten since succeeding Thomas Tuchel last month, was disappointed to see his side let their lead slip so late on, he thought a draw was "about right".
"It's disappointing because you're 1-0 up and you can see the end," Potter told Sky Sports. "But over the course of the game I think a point is about right.
"I don't know whether we did well enough to win it. Of course we got into the position to win it, but overall it was a really fighting performance from us.
"We improved a lot after the first 30 minutes and in the end we take what we get."
Casemiro's late heroics brought Chelsea's run of five consecutive clean sheets to an end, such is the defensive solidity they have shown in recent weeks. Potter, however, could not deny the quality of the Brazilian's late leveller.
The Chelsea boss continued: "We could've got out a bit more connected, but it's a great header. It only just went in.
"That's our first goal we've conceded in a while because it's dropped us two points. We have to appreciate the work ethic but adjustments need to be made as well."
