Spurs have been boosted by a £150million cash injection by owners ENIC as they look to back boss Antonio Conte heavily this summer.
The substantial extra funds will be used for investment both on and off the pitch, and will not add any interest to the club.
It comes two days after Conte led Tottenham to the Champions League with Sunday’s 5-0 win at Norwich.
Chairman Daniel Levy said: “The delivery of a world-class home was always a key building block in driving diversified revenues to enable us to invest in the teams and support our ambitions to be consistently competing at the highest levels of European football.
“Additional capital from ENIC will now enable further investment in the club at an important time.”
Tottenham are understood to be ready to meet their manager’s ambitions by delivering around six new signings.
