What happened between Cesc Fabregas and Alexis Sanchez got everybody talking.
Sanchez was bearing down on goal, and failed to convert with Fabregas mopping up the danger.
But as the Spanish midfielder was playing the ball out, the Arsenal attacker slid in from behind attempting to retrieve the ball.
He barely got the ball, hacking down Fabregas who reacted angrily, immediately getting up to his feet.
The Chelsea player then realised who it was, and hugged Sanchez before laughing off the incident.
