CASEMIRO did not hold back at Alejandro Garnacho during Man Utd's bore draw with Chelsea.
The Red Devils were in action at Old Trafford against the Blues in what ended up being a game void of quality.
However, there was talking point that got fans talking - and it involved United's South American pair.
Cameras caught Brazilian Casemiro screaming at Argentinian winger Garnacho.
The reason for the midfielder's reaction was very clear.
Former Real Madrid man Casemiro copped a booking for a late tackle, which he believed was Garnacho's fault.

Fans online speculated that it was because he was furious that Garnacho gave the ball away.
Worse still, he did not track back which frustrated his team-mate.
One wrote: "Casemiro has every right to shout at Garnacho there because that was absolutely f****** pathetic!
A second posted: "Casemiro rightfully shouting at Garnacho for giving away the ball & not tracking the ball.

A third added: "Casemiro just gave Garnacho a real bollocking after chasing back to stop a Chelsea counter after the youngster had given the ball away.
A fourth shared: "Garnacho deserve that rage scream from Casemiro. He wasted too much chance tonigt and not tracking back, that's unacceptable attitude.
While a fifth was of the opinion: "I hope Casemiro slaps Garnacho in the changing rooms after this match."
It was a frustrating day for the Red Devils who were unable to follow up their midweek 5-2 victory over Leicester City in the Carabao Cup with three points against the Blues.

Man Utd ratings vs Chelsea
MARTIN BLACKBURN gives his verdict on the Red Devils against Chelsea
Andre Onana - 5
Will be disappointed not to keep out Caicedo’s equaliser.
Almost put Casemiro in trouble with sloppy early pass too
Noussair Mazraoui - 6
Key interception to prevent Neto getting in on goal late on and tried to support Garnacho where possible
Matthijs de Ligt - 6
Good early block to deny Palmer.
Late slip under pressure from Jackson almost proved costly.
Lisandro Martinez - 6
Lucky not to concede a pen with clumsy challenge on Colwill and lucky to escape a red for x-rated late tackle on Palmer.
Diogo Dalot - 6
Poor tackle on Pedro Neto earned a deserved booking and had a real battle with his international team-mate.
Casemiro - 7
Made a difference with super ball to Hojlund in lead up to pen – but could he have got more distance on clearing header that was despatched by Moises Caicedo.
Manuel Ugarte - 6
Rugby tackle on Palmer but Uruguayan showed signs he is starting to settle in after big money summer move.
Alejandro Garnacho - 6
Always a threat but wasted some great chances.
Shot straight at Sanchez and shanked another effort after great work by Fernandes.
Bruno Fernandes - 8
Created United’s best two chances for Rashford and Garnacho and then kept his cool to score from the spot.
Marcus Rashford - 6
Hit the angle with volley on stroke of half-time and saw another shot saved by Sanchez.
Better from the England man.
Rasmus Hojlund - 6
Did not touch the ball in the Chelsea box first half but when he finally did he won the penalty.
Subs
Amad Diallo (73' for Rashford)
A couple of nice touches but not much impact.
Joshua Zirkzee ('84 for Hojlund)
A couple of nice touches but not much impact.
Victor Lindelof ('84 for Ugarte)
Thrown on to keep things tight and did that.
After a disappointing first half, it looked United had sneaked a win with a Bruno Fernandes penalty in the 70th minute.
However, they were pegged back just four minutes later when Moises Caicedo volleyed the past Andre Onana.
United are up to 13th in the league after earning a point.
