Bale was outstanding in the 3-1 win.
"He’s an amazing talent, an amazing player," Redknapp told the Spurs website.
"He’s got the ability to run all day, to beat people, to dribble, to shoot, to head it. He can do everything, really. He’s a unique player, a special talent.
"He's a fantastic young player and a great lad as well. He’s got absolutely everything. There isn’t a weakness in his make-up as a footballer.
"We’ve a lot of good players and it was a great team effort. I thought the pressing, the work the lads put in, you have to work that hard against Swansea if you want a result and we did that."
