We all have our own opinions on the amount of money involved within football, whether it be the price of match tickets or the amount of money players earn.
But has spending gone too far in the beautiful game and have players got too much power over clubs? We've witnessed over the years transfer windows in England alone reaching over £1bn, in ONE window.
Kepa Arrizabalaga became the worlds most expensive goalkeeper recently when he was signed by Chelsea for £71.6m, beating the previous record set by Liverpool weeks before when they signed Brazilian goalkeeper Alisson Becker from AS Roma for £67m. But should they have both spent such money on these two goalkeepers? In 2001, arguably the greatest goalkeeper in the world Gianluigi Buffon was signed by Juventus for, a world record fee at the time for a goalkeeper, £33m. An astonishing, £34m-£38.6m difference.
In 2017, Neymar became the world's most expensive footballer signing for PSG from Barcelona for £200m, a transfer fee we'd never have imagined for a single player. That transfer fee alone would have signed Zinedine Zidane 4 times over, when he was signed by Real Madrid for £50m in 2001, a world record at the time.
Luis Figo, Paul Scholes, Ronaldinho, Ronaldo Lima. If these players were still playing, in today's market it's unbelievable to think how much they'd sell for given many players today have buyout clauses reaching almost £1bn.
From the days of managers such as Sir Alex Ferguson, Brian Clough and Alf Ramsey putting players in their place and not allowing them to dictate the goings on at clubs, we hear multiple stories of players having more power than management in today's game.
Most recently we've heard a rumour of Paul Pogba demanding Manchester United for an extra £200k a week to keep him at the club amid interest from Barcelona. Also, in 2017 Lionel Messi reportedly 'demanded' that the Barcelona board sack Luis Enrique or he will leave the club for China.
Thibaut Courtois managed to force a move away from Chelsea to Real Madrid earlier this month by refusing to report in for training having previously stated his desire to move. When he was unveiled as a Real Madrid player, he was pictured kissing the badge, even though he had previously played for rivals Atletico Madrid.
But this isn't the first time a player failed to report in for training to force a move to the Spanish giants, as in 2013 Gareth Bale was allegedly ordered by Tottenham Hotspur to report for training only for the Welshman to decline. Having previously rejected bids, Tottenham had no choice but to succumb to the demands and sell Bale. Even though both players forced a move away they still had the audacity to state that they were "thankful" for the clubs.
In 2011, Carlos Tevez made headline after headline for the wrong reasons. Failure to turn up to training, opting to return to his native Argentina. Roberto Mancini stated "he wanted him out of the club" after he refused to come off the bench in a Champions League match against Bayern Munich. He was then suspended for two weeks and was guilty of five breaches of contract then given a fine of four weeks wages only for the PFA to reduce it to just two weeks.
Raheem Sterling also requested to sit out of England's 1-0 win over Estonia in the 2016 Euro Qualifier due to 'tiredness' even though he has trained his entire life to make it as a professional footballer and raking in thousands a week.
Are footballers being pandered too much? Have players got too much control over clubs? Does Financial Fair Play come in to effect to certain clubs? It's only a matter of time before we see a big money move for a player reaching nearly £1bn and see them on weekly wages of £1m.
