Tottenham Hotspur striker Harry Kane says his loan spell at Millwall turned him into a man ahead of Sunday's FA Cup quarterfinal against the League One club.
Kane, 22, spent four months on loan at Millwall until May 2012, scoring seven goals in 14 appearances to help the club avoid relegation from the Championship.
He was voted the Lions' Young Player of the Year, and he faces Neil Harris' side on Sunday as one of the most feared strikers in Europe.
"I had a great time at Millwall, I enjoyed my loan spell there. I was 18 at the time, playing in the Championship. It was big part of my development," Kane is quoted as saying by the Ham and High.
"We were in a relegation battle and it really probably turned me into a man, playing in difficult, high-pressure games -- and I managed to come out of it positively.
"It will be interesting to play them again. A lot has changed since I left, but I'm looking forward to it."
The match will the last cup game at White Hart Lane before the stadium is demolished in the summer, and will be the first competitive meeting between the London rivals since April 1990.
"The atmosphere is going to be amazing, of course with it being a quarterfinal as well. It's a big game," Kane added. "The fans have been fantastic and it's important we win, get to the semifinal and see who we get."
