Daniel Levy's 18-year tenure at Tottenham Hotspur has just taken a dramatic turn. 

Since 2001, the chairman has sanctioned an average of £5million spending per transfer window and prevented Mauricio Pochettino from signing players for an entire year. 

So naturally, he's appointed Jose Mourinho. 

The first manager ever to break the £1billion mark will take charge in time for Saturday's trip to West Ham. 

The question many Tottenham fans will be asking is how the Portuguese will work alongside Levy. 

He's won three Premier League titles, as well as two in Serie A and one in La Liga, but none of them have been managed under the sort of constraints Pochettino has dealt with. 

However, it's being widely reported that Levy is finally willing to change his approach. 

Mourinho will have money to spend. Somewhere, locked away deep in the coffers, is a bigger budget than the board would have us believe, especially having recently re-financed some of the loans used to build the new stadium. 

That means they were also able to tempt their new head coach with a huge contract. 

The 56-year-old will earn a staggering £15million-a-year, per the Daily Mail.

The deal will see him until the end of the 2022/23 season. 

That's almost double what Pochettino was on, even after the Argentine had signed an extension in May 2018, which was mainly aimed at securing his backroom staff pay rises.

In light of that, it has cost the club £12.5million to sack him.

For a chairman so notoriously prudent, this must have been a painful 24 hours. 

Yet he must have the utmost faith in Mourinho's abilities to turn things around if he is willing to fork out so much. 

In a statement, the new man in charge said: 

"I am excited to be joining a club with such a great heritage and such passionate supporters.

"The quality in both the squad and the academy excites me. Working with these players is what has attracted me."

The prospect of picking up over £1million every month must also be an exciting one. Whatever has happened in his last two spells in English football, the Special One still has an aura unmatched by most. 

For perspective, only Pep Guardiola, on £20million at Manchester City, earns more in the Premier League. 

It represents a huge statement of intent from Tottenham. 

Now Mourinho's task is to repay that faith.
