Man Utd fans spot what Manuel Ugarte and Lisandro Martinez did to Kai Havertz after Arsenal penalty miss which wasn't shown on BBC

Manchester United fans have spotted what Manuel Ugarte and Lisandro Martinez did to Kai Havertz following Martin Odegaard's saved penalty which wasn't shown on BBC.

Man United beat Arsenal 5-3 on penalties to book their spot in the FA Cup fourth round.

Bruno Fernandes opened the scoring before the Red Devils were reduced to 10 men following the dismissal of Diogo Dalot, who received two yellow cards.

Gabriel levelled proceedings as Odegaard had the chance to put his side in the lead when Harry Maguire was adjudged to have fouled Havertz, with the Man Utd defender raging over the decision.

But Altay Bayindir produced a fantastic save to deny Arsenal a goal.

As Havertz followed up for an attempted to rebound, Ugarte, who clashed with the German following the award of the penalty, and Martinez both barged into him, clearly not forgetting what happened moments before the spot-kick.

Ugarte and Martinez's reaction to Havertz following Arsenal's failed penalty got Man United fans online talking.

One X user wrote: "We need more South Americans in this team."

A second said: "Man I fucking love Ugarte."

A third joked: "Bring Back Marcos Rojo and it’s all out war on the pitch."

Another added: "I f**king love South American footballers."

Ugarte has shone since Amorim's arrival, having played under him at Sporting CP.

He appears set to play a crucial role in the Amorim era.

Speaking after the win, the Portuguese said Arsenal's penalty miss gave his side 'more strength'.

"It was really important because [it] gives us more strength, and then with less one player, he's really hard to press," he told the club's website. "It's really hard to press a team like Arsenal with 11 players, imagine with 10 players, and then you are in [a] disadvantage, [it] is really hard because they can control the ball. They were already controlling the ball in a lot of moments. So it was vital to win the game, to draw the game."
