Thanks to a 2019 transfer ban, Chelsea had spent an uncharacteristically low amount on new players of late. Owner Roman Abramovich changed that awfully quickly. He loaded up in the tiny offseason between 2019-20 and 2020-21, spending over £220 million on RB Leipzig forward Timo Werner, Bayer Leverkusen attacking midfielder Kai Havertz, Ajax winger Hakim Ziyech, Leicester City fullback Ben Chilwell and, later in the window, Rennes goalkeeper Edouard Mendy. The club brought in central defender and former Paris Saint-Germain captain Thiago Silva on a free transfer as well.
