Luiz red card changes the game
The turning point came in first-half injury time when Arsenal were leading 1-0 and were dominant.
Daniel Podence played the ball through to Jose and the Brazilian, on his home debut, had his heel clipped from behind by compatriot Luiz.
Referee Craig Pawson decided that Luiz had made no attempt to play the ball and sent the centre-back off. It was Luiz’s third red card for Arsenal after also being dismissed in the 2-2 draw at Chelsea in January 2020 and then again in the 3-0 loss to Manchester City in June.
