Alejandro Garnacho is condemned for “childish, childish” behavior while a former Arsenal player fumes over how he moves the penalty spot despite calls for punishment before Andre Onana saves Man United

Man United star Alejandro Garnacho was heavily criticized by former Arsenal midfielder Kim Kallstrom for his antics before FC Copenhagen’s missed penalty in the Red Devils’ 1-0 Champions League win.

The Danish side were awarded a penalty in the final minute at Old Trafford following a foul by Scott McTominay, giving Jordan Larsson the chance to secure a last-minute draw.

Larsson was denied by a great stop from Andre Onana as the goalkeeper dived to the left to preserve Man United’s slim 1-0 lead.

The footage showed that Garnacho had stomped on the spot with both feet before the penalty, while referee Marco Guida was busy dealing with the protesting players.

Garnacho’s actions were criticized by Kallstrom, who worked as a pundit for TV4 Play.

The former Sweden international, who played for Arsenal on loan in 2014, was criticized for “childish” behavior at Garnacho.

“What an ugly guy,” Kallstrom said, as reported by expresses.

“Ahh, I don’t know… That’s so childish. It’s so baby level.”

Host Olof Lundh responded by suggesting that Garnacho should be punished for his actions.

Both United boss Erik ten Hag and his Copenhagen counterpart Jacob Neestrup did not know what Garnacho had done.

“I did not see it. The referee probably didn’t see it either. “I don’t know,” Ten Hag told TNT Sports.

Onana’s decisive penalty gave Man United a decisive 1-0 win, boosting their hopes of reaching the knockout stages of the Champions League.

The goalkeeper’s stop provided a huge boost to his £47million move from Inter Milan after a difficult start to life at Man United.

Another much-maligned Man United star proved a hero that evening: Harry Maguire scored the only goal of the game.

Maguire headed home a cross from Christian Eriksen in the 72nd minute.

The England international admitted afterwards that he was “meant to” score the winner after a torrid year at the club.

Maguire still stressed that the evening belonged to a former Manchester United star and that the club was paying tribute to the late Sir Bobby Charlton.

Man United sit third in their group with three points but are now just one behind second-placed Galatasaray.
