Due to the COVID-19 pandemic, spending has been much lower during this market compared to previous years.

Manchester United confirmed their swoop for Atalanta ace Amad Diallo earlier this month while Arsenal have finally got Mesut Ozil off their books and signed Real Madrid ace Martin Odegaard on loan.
