There were no less than four new arrivals at the Academy of Light on Friday evening with some high-profile exits too after Ross Stewart, Danny Batth, Lynden Goocg and Elliot Embleton (loan) all departed the club.
With all the summer incomings and outgoings in mind, we take a look at just one of the ways Tony Mowbray could line up when every player – including new signings – is fit and available to play and take a look at Sunderland’s squad in general.
Take a look at Mowbray's new-look Sunderland starting XI and squad after a crazy deadline day of transfer signings and exits:
