George Weah played 15 games for Chelsea in the 1999-2000 season, before featuring nine times for Manchester City in the following campaign.
But the legendary Liberian explained on Monday night that he actually supports a different Premier League team.
Weah - who also represented Monaco, PSG, AC Milan and Marseille during his playing career - revealed at the Ballon d'Or awards ceremony in Paris that he had followed Tottenham Hotspur since he was a child.
The 58-year-old, who won the 1995 edition of the Ballon d'Or was a special guest at Monday's ceremony in Paris.
While on stage Weah was asked which players he most liked to watch.
He replied by pointing at former Tottenham Hotspur striker Harry Kane and saying: 'Yeah, that's one of my players that I love.
'I'm a fan of Mr Kane. When you were playing for my team, I'm a fan. I'm a very good fan because I believe that he's a very strong and very clever striker.
'I support the team... Tottenham, since I was a kid. I love him.'
Many fans watching the awards ceremony on television were quick to express their surprise at Weah's revelation.
One took to X (formerly Twitter) to write: 'Weah has been a Spurs fan this whole time and WE NEVER KNEW?'
A fellow Tottenham supporter added: 'No way George Weah is a Spurs fan, big up.'
Meanwhile, a Chelsea fan tweeted: 'George Weah supports Tottenham?!?!?! Wonder how he felt scoring the winner against them for us.'
Kane - who responded to Weah's praise with a wide grin - left Tottenham to join Bayern Munich in August last year.
But Kane is still Tottenham's all-time leading scorer with 280 goals in 435 games.
Kane came 10th in the overall vote for this year's Ballon d'Or.
The 31-year-old England captain also shared the Gerd Muller Trophy with Kylian Mbappe after they both scored 44 club goals last season.
Kane's 44 Bayern goals came in just 45 appearances, while Mbappe featured in 48 matches for PSG last season - before leaving to join Real Madrid during the summer.
Despite his incredible tally of goals, Kane failed to help Bayern win a team trophy in his first season in Germany.
However, Bayern currently sit top of the Bundesliga after eight rounds of fixtures this season.
