Controversial Football Incident Goes Viral: Nacho's Tackle on Kolo Muani Sparks Outrage

Even the experienced former Real Madrid defender might feel embarrassed when he sees images of his altercation with France's Randal Kolo Muani.

Nacho, aged 34, was captured on camera pushing the head of the fallen striker into the ground.

A photograph of the intense moment was described by one fan as the "most shocking football picture ever seen."

Nacho, who recently moved to Saudi club Al Qadsiah FC, appeared intense, with one hand on Kolo Muani's head while the PSG player had his eyes closed.

And with his other hand raised, Nacho prepared to push the 25-year-old's head down.

"Outrageous," remarked one fan, while another called it "so wrong".

Nacho had been drafted into the Spanish side only to replace the suspended Robin Le Normand.

The early altercation, for which he escaped punishment, suggested he was eager to assert his physical presence.

However, Kolo Muani responded perfectly, scoring to put France ahead just moments later.

Despite this, Lamine Yamal's stunning equalizer shortly afterward made him, at 16, the youngest scorer in Euros history.

Spain took the lead through Dani Olmo's deflected winner in the 25th minute.

As for Nacho, amid his team's jubilation at the end, he may reflect with some discomfort on his most controversial moment.
