Schalke midfielder Kevin-Prince Boateng admits he regrets his time at Tottenham.
Boateng is back in London tonight for their Champions League clash at Chelsea.
"I think everybody knows I had a difficult time when I arrived here," he said.
"I was young. I had the money. You come here at 20 and have to play for Tottenham, and it wasn't easy for me. I chose the wrong way because I was not experienced enough.
"At Portsmouth I showed what I could do, the kind of football I was capable of. It's good to be back. I love the city of London, I've seen a couple of friends, and I love the football culture."
