Redknapp wrote for The Sun: "They say a little love goes a long way… and I wouldn't argue with that when it comes to Gareth Bale.
"Even though he's been one of the best players in the world, Gareth has never really been a high-confidence kind of person.
"I know what a quiet lad he is and he needs to be made to feel important.
"If you're that way, confidence is crucial — and that reminds me of a tale Terry Venables told me, which proves it.
"When Terry made his debut for Chelsea he was delighted to be in the same team as his idol, a guy called Johnny Brooks.
"Johnny had played for a great Tottenham side, won a few England caps and was nearly 30.
"At half-time he sat next to Terry, who thought his hero was going to give him a few words of advice.
"Instead Johnny turned and asked, 'How do you think I'm doing?'
"Terry couldn't believe it. There he was, a 17-year-old playing his first game, and this England international was asking him!
"It just shows how some people don't have the confidence you imagine just because they're great players. I think Gareth is very much like that.
"We've seen over the past few weeks what a fantastic player he is — and he certainly had to wait for his chance.
"I'm not having it that it took five months until he was fit to play regularly.
"With Gareth playing like he is, you see that Tottenham forward line and if you're in the opposition dressing room you're thinking, 'Bloody hell, this is going to be a tough day'.
"There's Gareth, Harry Kane, Son Heung-min, Dele Alli, Lucas Moura… that's as good an attacking line-up as any in the country.
"The Arsenal back four will be looking at them ahead of the game and wondering how they'll cope, because it's been hard work for them at times this season."
