A previous spat between Dan Burn and Kai Havertz sparked the unsavoury scenes at the end of Newcastle United's 1-0 win over Chelsea
Havertz elbowed Burn in the 1-0 defeat at Stamford Bridge back in April and the Magpies defender savoured the moment at the end of the game at St James' Park. Havertz somehow avoided a red card for the incident back in the spring.
Burn said after the game: "It was the emotion of the game wasn't it? Me and Kai had a few run ins before and it's just part and parcel of the game. It can get the better of you at the times.
