Bale has had a mixed time of things since returning to north London, the forward having scored 10 goals and assisted three more in 25 appearances.
There had recently been talk of Bale staying on at Spurs after hitting form, but he was criticized by Jose Mourinho last week and played no part in Sunday's win at Aston Villa.
And with a year still to run on his Madrid contract, the forward believes he will be back in the Spanish capital after representing Wales at the rescheduled Euro 2020 tournament.
"It's no distraction," he said at a news conference on Tuesday previewing Wales' opening World Cup 2022 qualifier against Belgium.
"The main reason I obviously came to Spurs was I wanted to play football, I wanted to be match fit. The original plan was only to do a season.
"After the Euros, I have a year left at Real Madrid. My plan is to go back."
Wales' preparations for Wednesday's clash with Belgium, the world's number one ranked nation, have been disrupted by a number of injury withdrawals.
Having already lost Juventus midfielder Aaron Ramsey from their initial 31-man squad, Tottenham's Ben Davies and fellow defender Tom Lockyer pulled out on Tuesday.
It is a big blow for Rob Page as he once again takes caretaker charge of Wales in the absence of Ryan Giggs, who remains under investigation due to an allegation of assault, which he denies.
"It's not great news for us, two defenders getting injured prior to camp," Page said. "We've assessed them and they're no good. It's not ideal preparation. We’ve got to react to that and pick a team that we think will win us the game.
"I think they're quite significant injuries. It's a shame. But we have to deal with it."
Page also took charge of Wales' three fixtures in November – a friendly draw against the United States, followed by Nations League wins against the Republic of Ireland and Finland.
Skipper Bale has been impressed by Page's work in the last two camps but is eager for the situation regarding Giggs to be resolved before the Euro 2020 finals.
"Pagey has done an incredible job. He's addressed the situation amazingly well and kept the consistency," Bale said. "There are no excuses. We've had another good couple of days and we're fully focused. We're ready to go.
"I think my influence has been the same. We're just trying to keep it the same. Nothing has changed. Going into the Euros, ideally things are sorted, but we understand the situation. The FAW [Football Association of Wales] will be in charge of that, not the players."
Asked about his fitness, having been benched against Dinamo Zagreb and not used at all versus Villa three days later, Bale said: "I didn't play Sunday but I've had a couple of days' training.
"It's been a quick turnaround. Same for every country. Everyone is in the same boat – we're ready to go.
"It's probably the most match fitness I've had. I'm feeling fresh and ready to go."
Wales have won their opening group match in just five of their 18 World Cup qualifying campaigns, although they have done so in two of the previous three.
The Dragons are unbeaten in four games against Belgium, famously beating their next opponents 3-1 in the Euro 2016 quarter-finals.
But Belgium enter the match in Leuven in great form, winning 23 of their past 24 qualifying matches since going down 1-0 to Wales in June 2015, and Bale is predicting a tough opening Group E test.
"We know Belgium is a great team and we know we're going to be the underdogs," he said. "But you don't need to be the best team to win a game.
"This is why football is so great. What we showed that night [at Euro 2016] was more heart, desire, belief. When we pull on the Welsh shirt, we believe we have more passion than anyone.
"I think beating a big nation in a qualifier gives us confidence to grow. When you enjoy winning, it breeds more."
