Kevin-Prince Boateng concedes that he's had to change his lifestyle as he attempts to get his career back on track.

Following his move to England from Hertha Berlin, Boateng endured a difficult time in his early days with Tottenham Hotspurs.

The 23-year-old revealed how his lifestyle spiralled out of control at Tottenham but he now says that's in the past with all his efforts now geared at putting himself out there as a true professional.

The midfielder who has helped Portsmouth reach the FA Cup has been reflecting on his past and says he was knocked off during his introduction to Martin Jol, then Spurs manager.

"I will never forget that first meeting with the manager. He sat me down in his office and told me I had been signed by Tottenham, not by him. He said he was sure I was a good guy, but I wouldn't be playing in his team. It knocked me flat, and I suddenly felt very alone. I needed a release and I found it in London's night scene," the player said.

From then on, Kevin-Prince Boateng's career never looked like getting off the ground.

"I was out all the time, and parties and nightclubs soon became more important to me than the football. Every day, I would get back from training and start thinking about where I was going that evening. I got through an unbelievable amount of money.

"I was in another world. I can't say it was a happy one, and I even lost my driving licence for speeding at one stage. No-one tried to stop me, so I just carried on.

"It was no better during the day. I remember going out one day and buying a Lamborghini, a Hummer and a Cadillac, all in the space of a few hours."

But he says something has changed now as he gets his career on track.

"It was crazy, but I have finally changed my life. I'm now putting away an amount from my wages every week, so I will have some savings to fall back on, and the cars are going to have to go. I'm selling those, and I'm getting my career back on track, wherever it might take me."
