Three of the five most expensive Premier League transfers were completed last summer, with Jack Grealish's move to Manchester City from Aston Villa for an estimated £100m breaking the competition's transfer record.

Liverpool, Man City and Arsenal only feature once in the top 10 when it comes to most expensive transfer fees, while the list is completed with three entries from Chelsea and four from Manchester United.
Liverpool's signing of Virgil van Dijk ranks 7th while Arsenal's deal for Nicolas Pepe is ninth. Man United's signins of Paul Pogba, Harry Maguire and Lukaku come in at third, fourth and sixth respectively.
