Sunderland boss Simon Grayson accepts some members of his squad could move on before the transfer window slams shut at the end of next month.
The Black Cats have seen Jermain Defoe join Bournemouth and keeper Jordan Pickford make the move to Everton since their relegation from the Premier League.
Vito Mannone seems set to be the next out the door after Championship rivals Reading made a move earlier this week and Grayson is anticipating further departures.
“That’s just part and parcel of it. I knew that when we came to the club and we accept it,” he told the Sunderland Echo.
“We have got recruitment in a good place at this moment in time, we’ve got players lined up that if someone goes out we can look to try and bring in. That’s the case right through the squad.”
A new keeper will now be a priority for Grayson as he will be left with just Portuguese stopper Mika should Mannone exit the club.
The 26-year-old moved to Wearside last summer but failed to make a single appearance as he was behind Pickford and the Italian in the pecking order.
Grayson has brought in attacking pair Aiden McGeady and James Vaughan since he replaced David Moyes as the club’s manager earlier this summer.
Sunderland are 2.30 to beat Derby County in their season opener on August 4 and 15.00 to win the Championship outright.
