Bale believes the experience of playing in the Champions League has helped them kick on in the Premier League this season.
He told Sky Sports 1: "We've learnt a lot from last year being in the Champions League."
Bale claimed he did not lose faith Spurs would win the game after failing to take a number of chances in the first half.
He added: "As long as we are creating chances that's the main thing.
"We were confident we would get one whoever it fell to and lucky enough it was me."
