“Ive had approaches from people where people want this because this is one of the most attractive football clubs in the world to buy,” said Donald. “The fan base, the passion, the history, you can create a Premier League brand here.
“Ive read in the paper the Qatari guys who own PSG are interested, I dont know if its true because weve not spoken to them.
“If they picked up the phone and said we want to do a Man City and take Sunderland to the next level and go boom it wouldnt be fair of me to hold it because I like it, and I do love it.
“But if there are people who knock on the door and say that, then that might be a game changer but we havent had that.
“Weve had approaches from people who I dont think at this stage, some of them, are going to do it any better, any different, in fact might penny pinch more.
“If you say Im a penny pincher, Im tight but Im trying to get value for money. I dont think Ive passed up an opportunity for Sunderland.”
Donald revealed the Black Cats will still have around £14million to pay for players contracts next season, significantly more than any other team in League One.
One way to address that would be to bring in new investors, yet Donald believes there are other ways to raise money.
When asked if the club could bring in more investors to help raise funds,Donald replied: “Potentially, what Ive done with Charlie (Methven) and Juan (Sartori) is weve been working, if you like, on the other Championship teams models because we think were ok in League One.
Donald also stated any potential investors would have to share the same motives and want only whats best for the football club, rather than wanting to “treat it as a toy.”
He also believes there are other ways to raise funds through various strategies, such as the Netflix link, stadium naming rights and the clubs academy.
“You could get an investor comes in and says Ill put £60million in but fundamentally that would be £60million worth of debt,” said Donald.
“So would we be better to raise £30million ourselves and spend it without any involvement? Maybe but its a bit more of a gamble and puts the pressure on us to get it right.
“When Im talking about do we need investment, we might not, there are ways that our revenue might go up, but we want a buffer.”
Donald also revealed another option would be for co-owner Juan Sartori to get more involved with the club, after buying a 20 per cent stake last summer.
“What we have got to do is recognise if Juan wants to, and those conversations are ongoing, it might just be that Juan gets more involved,” added Donald.
“But on the basis that things arent certain yet, youve got to bare in mind that if Im going to say to Juan can we have a bit more finance and firepower please he might turn around and say yeah Ill do that but I want a bit more of the club Stu, whats it worth?
“We have to get a market feel of where we are so that Juan would invest on an equitable basis if thats what he wants to do.”
