The Wales international suffered the highs and lows of football in the space of a few days following the 4-2 defeat by Bolton at the Reebok Stadium.
The result came on the back of Bale's outstanding performance in the victory against holders Inter Milan in the Champions League.
Redknapp said: "There was nothing wrong with Gareth today. He was probably my best player.
"He had some fantastic runs and crossed a couple of great balls. If people had got on the end of them he could have made two or three goals.
"I do not expect the kid to keep doing miracles. He will have good days, bad days. He is a young lad, a left winger. He has been fantastic for us and is improving.
"He will be marked very tight and people will make it very difficult for him. They are not going to stand off him and let him do what he wants to do. That is what he has to cope with."
Bolton, defeated by Liverpool at home last weekend, went 3-0 ahead thanks to two goals from Kevin Davies, one from the penalty spot, and Gretar Steinsson.
Tottenham, however, staged a rousing comeback with Alan Hutton and substitute Roman Pavlyuchenko scoring in the final 11 minutes before Martin Petrov stepped off the bench to seal the points for the home side.
England manager Fabio Capello took in the game and Bolton boss Owen Coyle believes Davies deserves more caps.
Coyle said: "Kevin Davies ran the game from the first whistle. He dominated the game. If he wasn't scoring he was knocking things on.
"The great thing about Kevin is he does not have to score goals to contribute to a game but when he does it takes him to another level. He was unplayable.
"I think it was nice Mr Capello was here. He would have seen Kevin and Gary Cahill, who was outstanding at the back, as well as Fabrice Muamba.
"It is great to have English players in your team because this is the country in which we operate.
"It is not for me to tell anyone their job but you see Kevin's performance today and it was outstanding. The reason I took him off was to give him a standing ovation."
Redknapp had to do without with Rafael Van der Vaart and Aaron Lennon who both have hamstring injuries - they could also miss the Sunderland match on Tuesday.
The Spurs boss was disappointed at the way his team caved in after the glorious victory in midweek.
He said: "The goals we shipped were poor goals. Owen got the absolute maximum out of his team today.
"The game was as I expected. They got after us. They weren't going to stand off us and let us play. They worked their socks off and made it difficult for us.
"You have got to go for it when you are 1-0 down but we became very open and did not give enough protection to our back four."
