Stewart Donald was asked if Sunderland were for sale 10 days ago after an interested buyer caught a glimpse of the Sunderland 'Till I Die documentary.

The Oxfordshire-based businessman has seen the Black Cats' global profile increase following the release of the popular Netflix series after completing his own takeover in May

Produced by Fulwell 73, the eight-part documentary followed the fortunes of the club during their relegation to League One last season and has been praised for capturing fans' special relationship with Sunderland.

And, ahead of Sunderland's Checkatrade Trophy Final against Portsmouth at Wembley on Sunday, Donald revealed it has even generated takeover interest.

"It's not secret that we've got to have a look at how we structure ourselves when we hopefully get in the Championship at some point to see how we compete with these teams at the top so I'm looking at loads of different ways to see how we can do that but naturally when you do that and talk to people, that sort of opens up enquiries to us anyway - and we've had loads," he told BBC Newcastle.

"I had one, funnily enough, about 10 days ago where somebody said the first he had seen of us was in a bar in Mexico in his hotel when he came down in the morning for his breakfast and Sunderland Till I Die was on. He loved the programme and he was interested in the football club. 'Any chance we're for sale?'

"I think the thing is: Sunderland is always going to attract interest because it is a huge football club and when you look at the big football clubs in this country, most of them are tied up and very difficult whereas if you look at Sunderland, Sunderland would be one that's perceived as one that's good value for money, easily attainable some people would say in relation to a Man United or a Man City.

"It's a huge, huge club so it's always going to attract interest so when you throw Netflix on top of it and you show the passion of the place then I think anyone who wants a football club will look at Sunderland. Then, of course, we look like we're turning around and have got some momentum and that makes us look even more attractive. It always is but I think especially with Netflix and how we're doing - even though we're down in League One - I think we look ever such an attractive proposition - which is great.

"That's not just investors; that's players, that's everybody so I think Sunderland, I hope and feel, has got a really good vibe and feel about it and that's attracting everybody from all over the place whether that's fans, players or investors."
