JACK Powell has turned his back on West Ham and said: I've proved you wrong.
Powell was released by the Hammers before Millwall snapped him up on a free transfer last year.
And the 20-year-old is already playing first-team football for the Lions – barely a year on from his Upton Park exit.
The midfielder grabbed an assist on his league debut against Blackpool last weekend and his performance was hailed by manager Ian Holloway after the 2-1 win.
Having failed to make the grade with Millwall's biggest rivals, Powell admits forcing his way into the senior ranks at The Den has tasted even sweeter.
"It's satisfying to prove West Ham wrong – even more so because I'm playing for their biggest rival now," he told the Southwark News.
"I didn't come to Millwall to rub it in their faces but it's worked out that way and I couldn't be happier.
"When I was younger I was at West Ham, I was committed to playing for West Ham and I supported West Ham but I've moved on now.
"I play for Millwall, I'm fully committed to Millwall and I support Millwall. I've moved on very quickly from being the person that I was at West Ham to the person I am now for Millwall.
"My family supports Millwall now as well. West Ham is my past and I've put that behind me."
Powell was given a rousing reception by the Den faithful when he was substituted during Saturday's win.
"Coming off to that sort of ovation was unbelievable," he said.
"Obviously I didn't want to come off but there are positives and negatives in every situation and the positive was that I got to experience the atmosphere and feel the appreciation from the fans.
"I was really grateful for that. I don't normally get emotional but the ovation I got was a bit overwhelming, knowing that all of my family were there. It was crazy.
"It was the sort of thing you dream of as a young player wanting to play competitive football. It was a great feeling."
