Martinez had only been booked moments earlier after tussling with Morgan Rogers, who had given Chelsea the lead at Stamford Bridge shortly after half-time with a mazy run through the entire United defence.

After VAR recommended a review, Bankes went over to the monitor and reversed his decision, before handing Martinez a second yellow card and told him to leave the pitch early.

But as Martinez trudged off, having been held back by his team-mate after confronting Moises Caicedo, Carrick could not look in the direction of his own player.

Carrick had his head down and was busy looking at his notebook, while in conversation with assistant Steve Holland, determining how the team needed to change tactically as they went down to 10 men.
