Arsenal striker Alexandre Lacazette was quick to show his concern after a collision with David Luiz that left the Chelsea defender needing a bandage.

In the dying seconds of the first half at Stamford Bridge the two competed for the ball.

Luiz emerged victorious and then tried to dribble the ball to safety. Lacazette kept the pressure on and as Luiz ventured towards the touchline gave his opponent a slight push.

It sent Luiz tumbling into a ballboy and over the hoardings.

Luiz, who held his wrist in pain after the incident, was quick to show his dissatisfaction towards Lacazette.

Despite only giving the slightest push, Lacazette showed his class by going to check on his opponent and offering him help to get back to his feet.

Luiz had clearly done some serious damage in the incident with his wrist heavily bandaged when he returned for the second half.
