According to sources, Frank will earn a salary of £8 million for the next three years, which is more than triple his previous earnings as Brentford's manager.
After spending seven years in charge of Brentford, including four seasons in the Premier League, Frank is leaving the club to take on this new challenge.
As Tottenham's manager, Frank will have the opportunity to experience Champions League football for the first time, thanks to the team's recent Europa League title victory.
