Since arriving from Real Madrid on loan, the former Spurs star has struggled for physical, mental and emotional fitness – resulting in a series of stop-start performances and cameo roles.
Now Mourinho feels the 31-year-old is in the best shape he has been since his return.
And from the moment Bale nonchalantly swept Dele Alli’s pass into the back of the Wolfsberger net from 18 yards for his goal on Wednesday night, he finally achieved his “freedom”, according to the Spurs manager.
“You could see from his goal on Wednesday,” Mourinho said. “It was a confident shot.
“A player with fear or negative feelings would never have hit that type of shot. To strike the ball that way, I think that strike means a lot.
“It means freedom. It means freedom in relation to the brain muscle. For this you need to be in a good condition.
“He looks happier than ever, he looks confident. In training you can see he has his confidence back, the way he hits his shots.
“If a player feels great, if he is playing 100 per cent and if the feeling are all good there are no psychological problems or fears or barriers.
“He is in the best condition since he arrived.”
Moreover after Dele Alli showed no ill effects after his 81-minute outing and Mourinho promised Spurs fans more of the mouth-watering prospect of Spurs fans seeing the Fab Four of Alli, Harry Kane, Heung-Min Son and Bale in action together soon.
So far they have only been on the pitch together for 13 minutes at the end of the 2-1 defeat to West Ham, but – fitness allowing – Mourinho plans to use them more in the run-in.
“They can play together and they will play together some matches for sure – unless something wrong happens to one of them, which I hope does not,” Mourinho said.
“But I don’t want to talk about Dele and Bale as it looks like I forgot Lucas Moura, Erik Lamela, Steven Bergwijn, Tanguy Ndombele, Giovanni Lo Celso and Vinicius. Because I don’t forget them.
“In relation to Dele, when you have players performing like he did, it’s easier for the team to play well.
“I’m happy with him. It’s been a difficult period. Sometimes small injuries in accumulation are more difficult than a big injury where after a few weeks or months you are back.
“Small injuries are mentally not good, players getting disappointed, lack of motivation, frustration.
“He went through all that. He came back.
“We had good conversations, trained and now he’s well, playing minutes or part of matches.”
Not yet a 90 minute match but he went through periods and basically now 75 or 80 minutes. We need everybody and in the particular case of Dele Alli I’m very happy.”
Probable Spurs team vs Burnley (4-2-3-1): Lloris; Doherty, Dier, Sanchez, Davies; Ndombele, Sissoko; Bale, Lamela, Son, Kane.
