Footage from inside Old Trafford has shown Michael Carrick's surprising reaction to Matheus Cunha's actions after Manchester United's stunning win over Roma.

A spectacular 90 minutes at Old Trafford saw Manchester United come back from being 2-0 down after 14 mins to beat Roma in the Champions League at Old Trafford on Tuesday night.

But, while the result puts an end to the club's dismal winless streak, it wasn't all good news as star forward Cunha received a red card that clearly hasn't gone down well with head coach Carrick.

Michael Carrick argues with Matheus Cunha immediately after Man United Champions League win

Alongside captain Bruno Fernandes, who scored a penalty to take the score to 2-1, Cunha was vital to United's comeback as his two goals ended up being what won them the match at Old Trafford.

His first came in the 83rd minute with the winning goal coming just three minutes later as Cunha whipped the ball into the back of the net before taking his shirt off a celebrating with the home fans.

Of course, the Brazilian was then shown a yellow card for taking off his shirt, a decision he later will have regretted after being shown a second yellow card, this time for a late challenge on Leonardo Balerdi, and therefore being sent off.

But that didn't stop Cunha from sticking around to watch the rest of the match and later running onto the pitch to celebrate the win his teammates and the fans in the stadium.

However, not long after he started celebrating did a clearly angered Carrick grab him and seemingly tell him to leave the pitch immediately, with footage of the moment showing a frustrated Cunha walking off while his teammates celebrate.

Why did Michael Carrick stop Matheus Cunha from celebrating Manchester United's comeback?

Initially, some fans may assume that Carrick did this as a means of punishment for him getting a red card which will rule him out of the next Champions League fixture against Sporting CP on November 25.

However, it may instead me to try and help Cunha from receiving a further punishment from UEFA for re-entering the field of play after his red card.

Under Law 12 of the IFAB Laws of the Game, a player who has been sent off must leave the vicinity of the field of play and the technical area.

This means that a dismissed player, in this case Cunha, cannot simply return to the pitch, even after for celebrations after final whistle, without permission.

Therefore, Carrick may have been acting in Cunha's interest when telling him to get away from all the attention of the celebrations, rather than acting out in anger because of the red card.

That being said, it remains very possible that Cunha could still receive further punishment for his actions following the red card.
