The 31-year-old forward has been struggling with a knee problem which he picked up while representing Wales during the last international break and the injury means he is yet to make his second debut for Spurs.
Tottenham head coach Jose Mourinho confirmed that Bale would not be in contention to feature against Manchester United in the Premier League this weekend but the sight of the attacker working on his fitness is a positive sign for the north London club.
Bale appeared in good spirits as he stepped up his work with the ball and took part in running drills with a member of Tottenham’s coaching staff.
‘Working hard,’ the Wales superstar posted on Twitter on Thursday morning.
Mourinho is hoping Bale is back up to speed with his fitness after the international break and is targeting Tottenham’s clash with West Brom on November 7 as a possible comeback date for the Welshman.
‘He’s working hard, very committed, very professional, very happy, but not yet for tomorrow or for the weekend,’ Mourinho said at his press conference on Wednesday.
‘I believe that the two weeks of the international break can be important weeks to his last phase of recovery and fitness problems, hopefully, to play when we’re back the weekend after the national teams.
‘We’ll see if it is possible to arrive there.’
Bale was left out of Wales’ squad for their upcoming Nations League clashes with the Republic of Ireland and Bulgaria but Ryan Giggs played down the severity of his injury.
‘We had conversations both with Gareth and the medical team and he’s just not right for this camp unfortunately,’ the Wales manager explained.
‘It [the injury] was picked up in the first game, and then he played the second game and it was fine. But then after the 90 minutes against Bulgaria, he just felt it a little bit.
‘It’s nothing serious, but it’s just one to keep an eye on.
‘It’s just taken a bit of time to settle down and he just wasn’t quite right.’
Wales take on England for a friendly before their Nations League matches and Giggs does not expect Bale to be in attendance at Wembley.
He added: ‘I think Gareth will be concentrating on his new club now and getting himself right for when he is fit and when he is available to play for Spurs.
