Cameroon manager Rigobert Song has confirmed that goalkeeper Andre Onana has left their 2022 World Cup squad due to “disciplinary reasons”. The 26-year-old is alleged to have been involved in a heated exchange with Song over his style of play during a training session on Saturday. Song is said to have criticised Onana for taking too many risks with his feet near his own goal and he wanted the Inter Milan shot-stopper to play more direct. After the match, Song confirmed that Onana has left the squad due to “disciplinary reasons” but the goalkeeper has been asked to return to discuss his situation. Speaking at a post-match press conference after the draw with Serbia, Song said: “Onana is not in the Cameroon team for disciplinary reasons. “He asked to leave and we accepted it after telling him on Sunday that he was going to be a substitute.” Song added: “He is a very important player but we are at the World Cup and my role is to put the team first ahead of an individual. “He is one of the best keepers in Europe. This is not about his performances but you have to preserve the squad. “Maybe it was the trigger we needed for this performance (against Serbia). It was a big risk that I took, but I’m the dad of these kids so when I have to take risks and make decisions, I do that and I stand by what I do. “At the moment I’ve asked Onana to wait and we will see if he is going to stay with us. It’s up to him.”
