This season Millwall broke their club transfer fee record that they've paid for a player twice, firstly buying Tom Bradshaw from Barnsley for £1.25 million, and then a week later buying midfielder Ryan Leonard from Sheffield United for £1.5 million.[1][2] They also broke the record received for a player, selling George Saville to Middlesbrough for £8 million.[3] Millwall knocked out Premier League side Everton on the way to reaching the FA Cup Quarter-final for the eleventh time in their history. Millwall spent the majority of the season in a relegation battle, securing their place in the Championship with two games to spare at the expense of Rotherham. The season covers the period from 1 July 2018 to 30 June 2019.
