Joe Lewis and ENIC investment figures highlight the issues Mauricio Pochettino had at Tottenham

Tottenham fans have long called on Daniel Levy and Joe Lewis to splash the cash in their bid to compete for top honours.

Going close in the title race on a couple of occasions and reaching the Champions League final in 2019 under Mauricio Pochettino, supporters believe money needs to be spent if the club are to reach the next level and achieve their goals.

Calls have only got louder this summer after watching rivals Chelsea spend heavily in the transfer market with Hakim Ziyech, Timo Werner, Ben Chilwell and Kai Havertz all big-money arrivals at Stamford Bridge.

But what has Tottenham's spending been like over the past five years compared to other clubs when it comes to additional financing?

Football finance expert Kieran Maguire - Swiss Ramble on Twitter - has reported that over the last five years the current 20 Premier League clubs have benefited from £1.9billion net financing, with 81% (£1,569million) of that coming from their owners and the other 19% (£366million) sourced from banks.

However, their findings show how much it differs at each club.

With Chelsea topping the charts at a whopping £440million from their owner over the past five years, it's a rather different story when it comes to Spurs.

The club are in fact at the other end of the charts having repaid £40million preference shares, with Manchester United bottom of the rankings having paid £89million to their owners.

Tottenham do however come out on top when it comes to external financing.

Taking on £618million in external debt and paying back £57million in interest since the 2014/15 season, the club's total comes out at a huge £561million after taking out big loans in order to fund the construction of Tottenham Hotspur Stadium that opened in April 2019.

The vast majority of that money (£265million) was in the 2017/18 season, with a further £169million the following campaign.

Only four other clubs took out external financing and they were Leicester City (£55million), Crystal Palace (£32million), Aston Villa (£31million) and Sheffield United (£3million).
