The former Newcastle United flop has turned over a new leaf since returning to Ligue 1 and shone in 2017/18, scoring 22 goals and notching 11 assists in the league.
Spurs have raided Marseille on two previous occasions to sign Clinton N'Jie and Georges-Kevin N'Koudou. Neither of those players made an impact at all when they moved to north London, but it could be third time lucky with Thauvin.
Spurs supporters have greeted the news with scepticism though, given Thauvin's previous failings in the Premier League.
He only spent a season-and-a-half at St. James' Park and made 16 appearances for the club, scoring one goal in the League Cup.
He was loaned to former club Marseille in January 2016 and impressed enough to be granted a permanent move there, where he has proven to be a fantastic signing.
It may be that Thauvin's stint with Newcastle was too much too soon, but with a couple more years of experience under his belt, he might feel ready to give English football another go.
The lure of Bayern Munich could be difficult to ignore, with the club boasting a growing French contingent including Franck Ribery, Kingsley Coman and Corentin Tolisso.
