Erik ten Hag made his first signings since taking charge, with Tyrell Malacia arriving from Feyenoord before Christian Eriksen agreed to join on a Bosman free transfer, following the expiration of his contract at Brentford.
Ajax defender Lisandro Martinez's move was also finalised, as he became our third capture of the close season.
Casemiro made it four incomings when being paraded on the pitch before the game with Liverpool, before a deal was agreed with Ajax for Antony, and the Brazilian signed on deadline day.
Goalkeeper Martin Dubravka also joined, on a season-long loan deal, prior to the window closing.
