Eto’o, a larger than life figure in Cameroon and African football, and currently the country’s football president, has maintained an imposing presence around the Indomitable Lions leading to jitters from some quarters.“The president of the federation is passionate about football, he lives and breathes football,” Song clarified in a recent press conference.Ahead of their World Cup opener last week, Eto’o trained with the team in their final practice session before they played against Switzerland, a game they lost 1-0.“I would say sometimes he even wants to put on the jersey and get out on the pitch to play, because he wants to give everything. But that is not why my players didn’t score against Switzerland. The president is a gentleman who is very supportive.“He was a footballer himself, he lives, breathes and dreams football, but he does not put any burden or stress on our shoulders, no. The president is someone who is easy to talk to, he is open and we communicate a lot.”##NAJAVA_MECA_6843406##Cameroon and Serbia lost their opening games, with both nations aware another defeat would leave them struggling to make the last 16.
