What is he doing?“I cannot believe he has done that. Too clever for his own good. To do that is absolutely ridiculous.“He may never ever get another chance to score a winning goal in an AFCON final.”But Senegal took the lead early on in extra time through a rocket by Pape Gueye.It marked the first time Morocco have trailed in the entire tournament.The host nation have not been African champions since their solitary triumph 50 years ago in 1976.Meanwhile, Senegal’s 2021 victory is also the only time they have lifted the AFCON trophy.
