Conte will be out of contract at the end of the season and Tottenham are working on tying him down to fresh terms.
The Italian is happy at Spurs and his team are third in the league table, but he is yet to make up his mind about signing a new contract with the club.
Juventus are said to be keen on taking him back to Turin and there is talk of other big clubs wanting him at the end of the season.
But according to Italian daily La Repubblica, Tottenham are prepared to throw big money to hold on to Conte beyond the end of the current campaign.
It has been claimed that Spurs are ready to offer him a contract worth €20m per season until 2025.
Such a deal would make him one of the highest-paid managers in the Premier League and European football.
The north London club are also ready to promise him a transfer budget of €200m to spend in the transfer market.
Tottenham are desperate to make sure that Conte agrees to sign a new contract and stays on beyond next summer.
