The Premier League has been highly renowned for its extravagant spending in the transfer market over the past decade. On Forbes' list of the richest clubs, the majority are from the English top flight. The essence of spending that much could be due to the high demand of the players by other clubs, which could lead to an inflation in the price. Another reason could be due to the club's desperation to sign players in order to strengthen their squad. So without wasting any much time, let's discuss the most expensive XI of PL signings.Note: the season indicated in front of them is the season they got signed by their respective clubs.#1 Goalkeeper: Kepa Arrizabalaga (2018-2019 Premier League season)Brighton & Hove Albion v Chelsea - Premier LeagueKepa Arrizabalaga is the world's most expensive goalkeeper.

He also played a pivotal role in his team's Europa League triumph that season. He saved two penalties in the penalty shoot-out against Eintracht Frankfurt in the semi-finals. Chelsea eventually won 4-1 against Arsenal in the final.With the arrival of Frank Lampard as manager in 2019 after the sacking of Maurizio Sarri, Kepa's form drastically diminished. It led to him being dropped by Lampard in most games.Under Thomas Tuchel's tutelage, Kepa seems to be like a changed man, regaining his form and playing more games. But he is used as a backup keeper due to the arrival of Edouard Mendy from Rennes in 2020.So far, Kepa has kept 26 clean sheets in 80 games.#2 Center-back: Harry Maguire (2019-2020 Premier League season)Leeds United v Manchester United - Premier LeagueHarry Maguire officially became the world's most expensive center-back after he was bought by Manchester United from Leicester City in 2019 for £80m.
