AC Milan attacker Kevin-Prince Boateng has explained his decision to quit the Ghana national team.
Boateng surprised many when he decided to quit playing for his country after a splendid 2010 World Cup campaign, aged just 24.
"While I was at Borussia Dortmund, I could divide my time," he told Vanity Fair.
"However, with Milan I play in Serie A, the Champions League and Coppa Italia, so I can't do it anymore.
"My knee was injured six times and has undergone six operations. Even flying in a plane hurts because of the change of pressure. Therefore, I had to say goodbye to Ghana because I care about my health."
