Tottenham owner Joe Lewis and chairman Daniel Levy

Tottenham owner Joe Lewis has given the green light to Son Heung-Min being handed a Harry Kane-style mega contract, Football Insider understands.

The Bahamas-based billionaire is the man chairman Daniel Levy calls “boss” and has the final say on all financial matters at Spurs.

A Tottenham source has told Football Insider that Lewis has sanctioned what is a mammoth contract offer to Son, 28, worth £200,000-a-week plus performance-related bonuses.

Talks are advancing over a deal that the Londoners expect to be tied up by the end of this year.

Following the closure of the transfer window last month, Tottenham have made it a priority to extend the contract of Son.

His current deal runs until 2023 but the club hierarchy have agreed to reward him for his status as one of the club’s two outstanding players.

The plan is to catapult him straight into the bracket of top earners at the club alongside talisman and goal king Kane.

Levy and Lewis are very keen to avoid another situation in which a star player runs down his contract and leaves for a cut-price fee, just as Christian Eriksen did last season.

Son’s reputation as a Premier League and global sensation has been further enhanced by his brilliant start to the new campaign.

The 89-times international has already banged in 10 goals from 11 matches as well as supplied four assists.

Lewis, 83, is the majority shareholder of ENIC International Ltd, which controls Spurs, and is ranked by the Sunday Times Rich List 2020 as the 34th richest person in Britain with a personal fortune of £3.992billion.

He appointed chairman Levy, who has a 29 per cent stake in ENIC, to run the Premier League club in 2001 and it has become increasingly successful on the pitch in recent seasons.
