The transfer window is open once again, but this summer, things are expected to be different.

Due to the impact of the coronavirus pandemic, it's unlikely football clubs will be spending outrageous amounts of money - well, with the exception of Chelsea perhaps.

Over the last few years, we've seen transfer values inflate, with the likes of Kepa Arrizabalaga, Harry Maguire and Joao Felix all moving for over £70 million last summer.

But this year, it's unlikely football clubs will be forking out that kind of money. 

Now the transfer window is open, though, it's worth looking back at some of the record-breaking deals we've seen over the years. 

Transfermarkt have created a list of the most expensive moves of each season since 2000. Let's check it out.

2000/01 -  Luis Figo | Barcelona to Real Madrid - €60m 

Figo was 2000/01's record transfer

2001/02 - Zinedine Zidane | Juventus to Real Madrid - €77.5m

2002/03 - Rio Ferdinand | Leeds to Manchester United - €46m

2003/04 - David Beckham | Manchester United to Real Madrid - €37.5m 

Beckham was another big Galactico

2004/05 - Didier Drogba | Marseille to Chelsea - €38.5m

2005/06 - Michael Essien | Lyon to Chelsea - €38m

2006/07 - Andriy Shevchenko | AC Milan to Chelsea - €43.88m 

Shevchenko was a record signing for Chelsea

2007/08 - Fernando Torres | Atletico Madrid to Liverpool - €38m

2008/09 - Robinho | Real Madrid to Manchester City - €43m

2009/10 - Cristiano Ronaldo | Manchester United to Real Madrid - €94m

Ronaldo was a huge signing

2010/11 - Fernando Torres | Liverpool to Chelsea - €58.5m

2011/12 - Javier Pastore | Palermo to PSG - €42m

2012/13 - Thiago Silva | AC Milan to PSG - €42m

Silva was money well spent

2013/14 - Gareth Bale | Tottenham to Real Madrid - €101m

2014/15 - Luis Suarez | Liverpool to Barcelona - €81.72

2015/16 - Kevin De Bruyne | Wolfsburg to Manchester City - €76m

De Bruyne has been incredible

2016/17 - Paul Pogba | Juventus to Manchester United - €105m

2017/18 - Neymar | Barcelona to PSG | €222m

2018/19 - Kylian Mbappe | Monaco to PSG | €145m 

Mbappe is untouchable

2019/20 - Joao Felix | Benfica to Atletico Madrid | €126m

There are certainly a few crazy deals in there. 

Real Madrid dominate

For all this talk about transfer fees going crazy in the last decade or so, just look at what Real Madrid were doing long before that. 

Real Madrid dominated the naughties

Figo, Zidane and Beckham all moved to the Bernabeu as the most expensive deal of their respective summer. 

Those three moves alone cost the club €175 million - then a few years later they went to break more records by purchasing Ronaldo and Bale. Madness!

Chelsea arrive on the scene

It's also interesting to see just how much money Chelsea have spent over the years.

Sure, Drogba and Essien were hits - to say the least. After all, together they won two Premier League titles and four FA Cups. 

Chelsea have made some big signings

Then there's Drogba alone, who almost single-handedly delivered Roman Abramovich his most sought after prize - the Champions League. 

Money well spent, you could say. 

But step forward Torres and Shevchenko. Both of those strikers moved to Chelsea in record deals, but both were disappointing. 

Torres wasn't great at Chelsea

Neither man could replicate their best form at Stamford Bridge and would be seen by many fans as a waste of money.

But Chelsea aren't the only club to see big transfers backfire. 

Man City shock the window

We almost forgot about Robinho's shocking stint at Man City - he was so bad you almost forget he was the club's record signing when they were taken over in 2008. 

Robinho was a waste of money

But, City's other expensive signing has proven he's worth the money. When they paid €76m for De Bruyne, eyebrows were certainly raised. 

This was a player who had struggled at Chelsea, so many expected him to struggle upon returning to the Premier League.

Oh, how wrong were we? In the last five years, De Bruyne has become arguably the best midfielder in the world and he's been key to City's success.

Man City will dominate with De Bruyne

With the Belgian in midfield, they've won two Premier Leagues, the FA Cup and four League Cups. Surely it's only a matter of time until City secure Champions League glory. 

Who will dominate next?

It's fair to say a number of different clubs have dominated the transfer window in years gone by.

First, it was Real Madrid, then Chelsea and now to an extent, it's Manchester City and PSG. That's not to say other teams aren't spending big, though. 

PSG know how to splash the cash

With the 2020 summer transfer window now open, expect to see some big deals go through. But will any match previous records set in years gone by? It's hard to see, but only time will tell.
