The Frenchman had no intention of using the striker and allowed him to go on loan.
Jose Mourinho, an avid fan for many years, was desperate to sign the Welshman and Spurs thankfully obliged.
And Bale was more than happy to make the trip, but an injury has kept him from making his second debut so far.
But the 31-year-old has returned to training this week and could play against West Ham on Sunday.
Bale was all smiles when he was spotted with his new team-mates and there is a feel-good factor at Tottenham right now having beaten Manchester United 6-1.
However, former Arsenal star Keown has offered a word of warning.
He told the Daily Mail: “When I returned home to Arsenal after a seven-year absence, I found almost nothing had changed. Other than the odd modification, Highbury was the same as was the training ground.
“Gareth Bale is back at Tottenham after seven years in a brand new stadium and a state-of-the-art training base. It’s very different from what he’ll remember when he said goodbye in 2013.
“Basically the supporters are the same. I had to convince the fans – some weren’t happy that I left for Aston Villa in the first place.
“But Bale is back with open arms. It is the superstar who left to be able to win everything with Real Madrid.
“It’s his honeymoon period, but I’m sure he realizes the fans will be looking for something special from him on the pitch.
“I have found myself trying too hard in my first few matches and Bale has to be careful.
“Anyone who’s played in both the Premier League and La Liga will tell you which one is more demanding and the Welshman hasn’t played consistently for quite some time. ”
Bale has been through a rough patch with injuries over the years and Keown has insisted Tottenham have to be careful not to overload the Welsh international.
He added: “I’m sure Jose Mourinho will think about managing his minutes and the Spurs medical team will be there as well.

“They handled Harry Kane’s return after a serious injury with great care.
“Bale will have seen his new side tear Manchester United – the club he could have joined instead – and felt he had made the right choice.
“He’ll want to get on the pitch and join the party but he has to take it slow. At 31, he is young enough to achieve great things with Tottenham. “
