The 2018/19 season saw Chelsea break the transfer record for a Goalkeeper when they paid £71.6 million for Kepa Arrizabalaga, and finish the Premier League in a respectable 3rd place – albeit 25 and 26 points below Liverpool and Manchester City respectively.
In Maurizio Sarri’s first and only season in charge at the club, Chelsea made it to the 5th round of the FA Cup, and narrowly lost out in the final of the EFL Cup when they were beaten on penalties by Manchester City – who had already taken the Community Shield from them at the start of the season.
They went the distance in the Europa League though, finishing top of their group and going on to comfortably beat Arsenal 4-1 in the final.
