The 31-year-old will make his second debut for Spurs in the Premier League game against West Ham on Sunday.
Jose Mourinho believes Gareth Bale will be able to regain his best form from his time at Real Madrid once he starts his second home coming at Tottenham.
Bale returned to Spurs in September after joining Madrid in then world record transfer in 2013.
After recovering from an injury, the 31-year-old will register his second Tottenham debut against West Ham on Sunday.
Although his seven-year tenure at Madrid ended with Zinedine Zidane freezing him out, Bale won four Champions League titles and two La Liga championships with Blancos and was devastating on the road to his peak.
Mourinho believes that when put his past behind him at the north London he will still have the skills that made him the most expensive footballer in the world.
Mourinho said as cited by Sports Central: “When he reaches his continuity and when he reaches his normal intensity and dynamic, I think he can be the player that people saw, being decisive when he went to Real Madrid in a very similar position.
Bale wasn't the only player to join Spurs from Real Madrid this summer. Sergio Reguilon was also in mix. Mourinho said the left-back gave him positive signs of Bale's state of mind.
The former Chelsea manager said: “It’s great to listen from Sergio Reguilon, who shared the dressing room with him in Madrid, that Gareth looks a different guy. “So if he’s happy with us then he goes home and he can share that happiness with family; it’s the best thing that can happen to him.
Though Bale has the ability to play a variety of attacking positions, there is one spot that Mourinho said the Welshman prefers.
Mourinho continued: “One of the first questions in my first conversation with Gareth was ‘What’s your favourite position?’ I wanted to start from there and he answered. "Does that mean he will always be used there? No. Because he will play where the team needs him to play. “But he was very clear by saying that his favourite position is on the right. It’s not as a No.10, it’s not as a striker, it’s not any more on the left side like he did in the first years of his career at Southampton and Tottenham. His favourite position now is on the right side..
