Spurs finished second in the Premier League last season — but they start the new campaign top of the fans' shirt "rip-off" league.
Supporters must splash out £75 when buying tops from the club's shop — complete with the name and number of their favourite player.
Yet the same adult shirts for the top-flight clubs cost £54.99 on the high street, a massive difference of £20.
A Mirror investigation has revealed Spurs followers are being charged £60 for a shirt and £15 for a player name and number, such as homegrown hero Harry Kane and his famous No10.
But savvy shoppers can pick up an official jersey for a fraction of the club's price at bargain store Sports Direct.
Chelsea shirts come with a £73.95 price tag
Football insiders explained that the clubs have their hands tied over commercial shirt deals whereas the high street retailers have the freedom to set their own prices. Champions Chelsea are hitting fans with a £73.95 price-tag for a name-and-number shirt while Manchester City and Manchester United are third most expensive at £72.95.
Campaigners have called on the clubs to play fair and slash the prices.
Justine Roberts, boss of parenting group Mumsnet which campaigns for affordable prices for children's sports kits, insisted: "Our users have said overwhelmingly that they think kits are a rip-off.
"Top-flight clubs generate huge revenues — pricing more thoughtfully should certainly not be beyond them."
And the Football Supporters' Federation urged clubs to come clean about the shelf-life of expensive shirts. They want fans told in advance when they are going to be revamped.
Burnley are the cheapest club in the league for shirts at £50
A spokesperson said: "We have argued for a use-by date on shirts so fans know how long it will be before a new version is out."
The Football Supporters' Federation added: "Many fans do feel kits are
expensive and they are changed too often. A fair solution might be for manufacturers and clubs to incorporate a sell-by date into the label.
"Then fans who buy a kit know exactly what they are getting and how long it will remain current."
Burnley fans get the best value for money paying £50 for a team shirt with all the trimmings. Liverpool are the only top-four finisher and Champions League contender to offer shirts for under £70.
Fans are able to buy them at the club's Anfield store for £65 — the same price paid by Watford and West Bromwich supporters for their kits.
A Man Utd shirt will set you back £72.95
Former Premier League title holders Leicester City have a £63 price-tag for a shirt complete with a five letter name and two numbers — less than the £67.99 that fans of newly promoted Newcastle United must cough up for the same deal.
Premiership newcomers Brighton charge £60 for their shirts, Bournemouth insist on £59 while Crystal Palace fans must hand over £58 to wear their favourite club's colours.
Adult shirts at Stoke City and Swansea cost £57.
Tottenham, who recently sold Kyle Walker for £53million to Manchester City — a world record transfer fee for a defender — said no one from the club was able to comment.
