The Welsh superstar left Tottenham Hotspur in 2013.
Speaking to The Standard, Harry Redknapp has described former Tottenham Hotspur man Gareth Bale as a "monster" and reflected on what away fans used to sing about the Welshman during his time at Spurs.
The 26-year-old left Tottenham in 2013 after sealing a world-record £85 million switch to Real Madrid, where he has helped the Blancos to two Champions League titles.
It might well be a magnificent few months for the Wales international, who has netted three times in Euro 2016 as Chris Coleman's side gear up for a shock semi-final clash with Portugal tonight, with France and Germany contesting the other semi tomorrow.
Bale came to prominence at Tottenham under Redknapp, who decided to give the then left-back a chance on the wing, and later a free role, and the rest is history.
The veteran manager has reflected on what Tottenham's opposition would sing at the superstar, suggesting that the lyrics summed up his danger at the time.
"Gareth has so much ability he would have been the best left-back had he continued to play there. He became the best left-winger in the world instead and now he plays off the wing in a free role," Redknapp told The Standard.
"The funny thing was, when we did that at Tottenham in 2011-12, the away fans used to sing “he’s Gareth Bale, he plays on the left” because they wanted him back out there.
"But he has proved he can play anywhere. He’s a monster of player, just like Ronaldo, and a lovely boy, too."
