Kevin-Prince Boateng has blasted Portsmouth's "amateurish" medical care, reports The Sun.
The midfielder, who is sidelined with a torn ankle ligament, claims he will be out for weeks after having the injury mis-diagnosed by the rock-bottom Premier League club.
"At 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."
The German-born player, added: "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.
