Football over the past decade or so has grown exponentially in terms of revenues from commercial means, which has meant that clubs have been able to spend large amounts of money to sign players in the transfer window.
Here, we take a look at the most expensive XI in football history.
1. GK - Kepa Arrizabalaga - €80m
Chelsea made Kepa Arrizabalaga the most expensive goalkeeper ever when they signed him from Athletic Bilbao in 2018 and he will go down as one of worst transfers in Premier League history as he has struggled to adjust to life in England.
The Spaniard is most famously known for refusing to leave the field despite Maurizio Sarri wanting to substitute him, with the club keen to let him leave. However, not many clubs have shown an interest in him and the club are destined to accrue a big loss on him.
2. LB - Benjamin Mendy - €57.5m
Impressed by his performances for Monaco, Manchester City decided to splash the money for Benjamin Mendy and he has not lived up to his price-tag, partly due to a number of injury issues he has faced in his time in England.
The Frenchman has only managed to make 73 appearances in his four seasons with City, and is another who has failed to make a mark in England.
3. CB - Harry Maguire - €87m
Manchester United's capture of Harry Maguire from Leicester City in 2019 for €87million, made the defender the most expensive Englishmen and the most expensive defender in history of football.
While many have aimed criticism at the club for the amount of money they spent on Maguire, the centre-back for his part has established himself as one of the best players at the club.
While he still has a few areas to improve upon, there is no doubt that he adds experience, leadership and stability to United's defence.
4. CB - Matthijs de Ligt - €85.5m
Juventus beat a host of top European clubs to capture the signing of Matthijs de Ligt in 2019 and after a poor start to life in Turin, he has established himself as a key player for the club.
The Dutchman is only 21-years-old and will be expected to be a rock at the back at Turin for a decade to come.
5. RB - Joao Cancelo - €65m
Joao Cancelo arrived at Manchester City in 2019 from Juventus in a deal which saw Danilo go the other way and he has been revelation for the club, especially in European competitions.
The Portugal international is capable of playing in both flanks and is an ideal player that suits the style of Pep Guardiola.
6. CM - Frenkie de Jong - €86m
Another young Dutch player who is touted as a future great, Frenkie de Jong got his dream move to Barcelona in 2019 and since then has established himself as a key player for the Catalan giants.
The 24-year-old is capable of playing in a number of roles in midfield and is expected to be a force for the club as they look towards the future.
7. CM - Paul Pogba - €105m
Manchester United signed Paul Pogba in 2016 for a then world-record transfer fee of €105million from Juventus, and it is safe to say that things have not gone to plan for the Red Devils.
The Frenchman has had a mixed time at Old Trafford, excelling in moments, though inconsistences have plagued him in England. The midfielder has so far made 199 appearances for the club, scoring 38 goals and helping them win the Europa League in 2017.
8. CM - Philippe Coutinho - €135m
Philippe Coutinho pushed for a dream move to Barcelona in 2018 and his dream unfortunately turned to a nightmare, with the Brazilian struggling to make a mark at the Nou Camp.
The Catalan giants spent a staggering sum of money and he has been so poor for them that they are willing to sell him for 1/3rd of the fee that they paid for him.
9. RW - Ousmane Dembele - €135m
Another expensive signing that has not gone to plan for Barcelona has been that of Ousmane Dembele, with the Frenchman struggling with a number of injury issues at the Nou Camp so far.
The 24-year-old who is currently injured, has made only 118 appearances in four seasons, managing to score only 30 goals so far.
10. LW - Neymar - €222m
The most expensive player in the history of sport, Neymar left Barcelona for Paris Saint-Germain in order to leave the shadow of Lionel Messi and establish himself as the best player in the world.
The Brazilian has been brilliant when fit, scoring 87 goals in just 116 appearances, but his off-field antics tend to gain more traction and headlines.
11. ST - Kylian Mbappe - €145m
Touted by many to be the next best player in the world when Lionel Messi and Cristiano Ronaldo hang up their boots, Kylian Mbappe has been brilliant for both club and country over the past two-three years.
The 22-year-old has a staggering 132 goals in just 171 games for PSG, with Real Madrid understood to be willing to break the bank in order to lure him to the Bernabeu.
