The 41-year-old Cameroon federation president and ambassador for the Qatar World Cup flew into a rage after being approached as he left Brazil's 4-1 win over South Korea in Doha on Monday night.

The video showed the four-time African player of the year breaking free from people seeking to restrain him and kneeing the face of the vlogger, named as Sadouni SM.

The man fell back after being struck. Eto'o was pulled away and has not commented or been seen since.

A Cameroon federation official said that former Barcelona striker Eto'o did not want to speak about the incident.

The African football legend was surrounded as soon as he left the 974 Stadium where the round of 16 match was played.

Wearing a blue baseball cap, he is seen allowing selfies with some fans before he was approached by the Algerian.

It is not known what comment was made, but Eto'o handed his mobile phone to a man before surging at the vlogger to deliver the blow with his knee.

Sadouni SM posted a video online Tuesday that offered his side of the story.

Qatar's World Cup organising committee has not yet commented on the incident.
