The 68-year-old English businessman was the chairman of the North London club from 1991 to 2001.
Keys has listed Lord Sugar among the top 10 most important people in Premier League history, placing him at number five.
The former Sky Sports presenter has also told an interesting story about his English compatriot.
“There was some speculation that Sugar provided 'inside' information from the inaugural meeting of P Lge Chairman who were discussing TV proposals,” Keys wrote on his website.
“His Amstrad company made set top boxes. Sky needed them. Sky got the deal. Sugar sold set top boxes!
“Nothing was ever proven as to whether he tipped off Sky's then Chief Executive, Sam Chisholm, about the figure required to land exclusive 'live' rights for Sky!”
Lord Sugar was not popular among the Tottenham fans and was a controversial figure when he was the club’s chairman.
However, to this day the 68-year-old follows Spurs and is often found giving his opinion during matchdays.
For that, Lord Sugar needs to be respected. After all, not many club chairmen are like that.
Tottenham finished fifth in the Premier League in the 2014-15 season with 64 points from 38 matches.
Mauricio Pochettino’s side will be aiming for a top-four finish in the league next season.
