Real Betis signing Rafael van der Vaart says leaving Tottenham is the biggest regret of his career.

Van der Vaart left Hamburg for Betis this month.

"It was a little to do with everything," he told the Mirror over why he left Spurs.

"It was private things, but also when what's his name [Andre Villas-Boas] came he said to me 'you're not my number one' and I had played two years, like, unbelievable, so for me it was really strange that he said that to me. So then I said, well, it's better to leave and that is what happened.

"It was a stupid decision, the most stupid in my career to leave Tottenham. I absolutely regret it because it was the best two years in my football life.

"When you see that team, when you have [Gareth] Bale, [Luka] Modric, me, [Aaron] Lennon... it was an unbelievable team. I think every game we played we were the better side. We had a lot of possession and a lot of fun with each other.

"And Harry [Redknapp] — he was like your dad. I would give everything for that man; I was really sad when he left. I think the England job would have been the best job for him and also for England."
