The Scottish Premiership runners-up looked like they might lose their manager last month
Aberdeen boss Derek McInnes says he wants to move on from turning down the Sunderland job.
The English Championship side are still on the look out for a new manager after being rebuffed earlier this month.
Aberdeen have sold winger Jonny Hayes to Celtic and lost Ryan Jack to Rangers this summer.
McInnes says he's aiming to build on runners-up spot in the Scottish Premiership, and both cups, last season.
"Part of the assurances that I was looking for was for staying at Aberdeen was that we wouldn't be selling any more players - certainly not in this window," he said.
"That's the way it stands. We're key to add players because we feel enough have left the building."
Sunderland have been handed a difficult start to life in the Championship and will face Derby County in their opening game of the season.
They'll then have back-to-back away games against Norwich City and Sheffield Wednesday - the latter of which finished in the top four last season.
"I think [Derby County] is a fantastic opening game," Kevin Ball said of the fixtures earlier this month. "We've got a home game and the fact that it's a Friday night to kick off the season, I think we'll get a full house.
"That for me what makes it even greater. Our fans always have a fantastic contingency travelling away. They'll thoroughly enjoy it. The first games are always tough no matter who you're up against because you're trying to find your level."
