Enzo Fernandez and Chelsea sent a clear message to Mason Mount during the extraordinary 4-3 win over Manchester United on Thursday.

The Blues produced the latest comeback in Premier League history as hat-trick hero Cole Palmer scored in the 10th and 11th minute of stoppage time.

In an interesting sub-plot, ex-Chelsea star Mount had been introduced as a late substitute - and the Manchester United midfielder quickly became a target after the stunning turnaround.

Previously unseen footage shows Fernandez walking towards Mount and pounding the Chelsea badge on his chest, before getting right up in his opponent's face as they waited for the game to restart.

There was clearly no love lost between the two former teammates, who were also seen squaring up to each other and mouthing unsavoury comments earlier in the match.

Fernandez channelled the feeling inside Stamford Bridge after a chorus of boos greeted Mount on his return.
