Daniel Levy had admitted during a fans forum that Tottenham Hotspur could have the opportunity to bring Harry Kane back to the club.
The chairman revealed to fans that the club inserted a buy-back option in the deal with Bayern Munich, according to Football.London.
Levy open to Harry Kane return
Kane finally got his move away from Tottenham at the end of the summer transfer window, as the North London club agreed a deal with Bayern Munich.
The striker had been linked with an exit from Spurs for a number of summers, with moves to Manchester United and Manchester City both rumored.
However, Spurs were always keen to sell their star man to a non-Premier League club.
Kane has made an excellent start to life in Germany, as he has scored four goals and registered one assist in four Bundesliga outings.
However, the England captain comes up against a familiar opposition on Wednesday, as Bayern Munich clash with Man United at the Allianz Arena.
