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.
