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,'' Boateng said in the Sport Bild magazine.

''Now doctors in Cologne have confirmed that the ligament is torn and I will be out for weeks.''

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.

''In addition, from that time I still today have around 200 caps, around 20 leather jackets and 160 pairs of shoes. I had, because of my frustration, an enormous appetite for shopping.''

He remarked that he had ''no desire to train in the morning'' and sometimes ''squandered inconceivably large amounts of money in the nights''.

''But it all did not make me happy. I was broken, in another world,'' Boateng said.

Boateng claims he now has his life - and his career - back under control. Portsmouth's financial problems mean he is unlikely to be at the club for much longer, and he is keen on a move to a leading team.

''I know today that a high percentage of my colleagues are insolvent after their career,'' he said. ''That will not happen with me. I put a portion of my salary to the side. My cars have all been sold.

''Some top clubs are interested in me. My next contract will be with a top European club. A return to the Bundesliga would be super.''
