Portsmouth midfielder Kevin-Prince Boateng has described the medical care he has received at the club as "amateurish".
Boateng, who said he will be out for weeks with a torn ankle ligament, claimed in a German magazine interview that the injury was mis-diagnosed by Portsmouth.
"At my club Portsmouth my foot pains were diagnosed as a strain of the syndesmotic ligament. Now doctors in Cologne have confirmed that the ligament is torn and I will be out for weeks." Boateng said in the Sport Bild magazine.
The German-born player, who has committed to playing international football for Ghana, said: "The World Cup is not in danger, but I had tears in my eyes. Earlier I myself was responsible for the setbacks in my career, now the medical support is amateurish.
"I am mad. At Portsmouth we don't have the level of medical care like there is at (Boateng's former German clubs) Hertha Berlin and Borussia Dortmund."
Boateng has, though, credited Portsmouth manager Avram Grant and former boss Paul Hart with helping him get his career back on track, saying he has his "life back under control".
The 22-year-old moved to the south coast last August from Tottenham, where he admitted his career stalled after joining from Hertha in 2007.
Boateng explained how he lost his way after then manager Martin Jol told him he would not play for Tottenham under him.
Boateng said partying became more important than football and he went on huge spending sprees - even buying three cars in one day.
"The best clobber was important to me - and that I was known in nightclubs. It got completely out of hand," Boateng said. "I bought three cars in one day. For a high six-figure sum I got a Lamborghini, a Hummer and a Cadillac Oldtimer."
