Manchester United chief Darren Fletcher has been accused of communicating with Ralf Rangnick during the club's 1-1 draw against Chelsea.
The Red Devils, under the stewardship of caretaker manager Michael Carrick, secured a point at Stamford Bridge after Jadon Sancho's opener was cancelled out by Jorginho's penalty to bring the hosts level.
And United technical director Fletcher, also in the dugout, was pictured during the game using an earpiece, with some suggesting he was talking to incoming interim manager Rangnick to discuss, for example, tactics or substitutions.
The side included some surprising changes, with star forward Cristiano Ronaldo left on the bench and Bruno Fernandes up front in an unfamiliar 'false nine' role.
