David Luiz enjoyed cracking Willian neck a bit too much

Unless you're a medically qualified physiotherapist - or Mr Miyagi - you probably shouldn't try this at home.

Life is good at Chelsea at the moment. The Blues are sitting pretty at the top of the table, with a commanding six-point gap between themselves and closest rivals Liverpool. A record 12 victories on the trot is a testament to Antonio Conte's expert management and the spirit within the camp. Central to the atmosphere both on and off the pitch at Stamford Bridge is a certain David Luiz. For so long mocked as a figure of fun and constantly dismissed as 'not a natural defender', the Brazilian has been in largely imperious form this term and is finally receiving the credit he deserves. But whilst Luiz's fine form is turning the heads of former critics, the player himself took great delight in a swift twist of teammate William's cervix. It was all fun and games until an audible snap shocked Willian and pleased his afro-haired pal no end. It seems Diego Costa isn't the only player in Chelsea who's in danger of losing his head...

Also at Chelsea training today, David Luiz & Willian have been having some fun... pic.twitter.com/UD5nJXPwIq
