Tottenham boss Redknapp admits gaffe selling Boateng to Portsmouth
Boss Redknapp said: "When I arrived last year, Boateng was injured and he'd had a few problems.
"I didn't really know much about him but I was listening to what other people were telling me about his character. They weren't painting a very good picture of him.
"I ended up asking myself 'Do I need him around here if it's true?'
"Yet, on the pitch, I thought the kid could really play and I wasn't keen to sell him.
"But we got what the chairman considered a good offer. Maybe the boy needed to move on."
