McClure is a lifelong Sheffield Wednesday fan, despite a family history with Everton too.
“My father’s side of the family are actually Everton fans because my grandfather’s brother, Joe McClure, played for them in the 1930s, in the same team as Dixie Dean,” Jon told BBC Sport.
“But it’s always been Wednesday for me. My Nan played with the players when they brought back the FA Cup to Sheffield in 1935, so I think she was a proto-WAG.”
Jon is desperate to see the Owls return to the Premier League after being relegated in 2000 – but can their manager, Danny Rohl, get there first, after being linked with a move to Southampton?
“It’s been a long winter,” added Jon. “We’ve come close to a comeback a couple of times down the years but we’re worried about losing our manager at the moment, because he’s so popular with Southampton.
“We love Danny, because he has been a talent for us, our problem is our chairman Dejphon Chansiri who is not a bad person but he is disappointing because he does not listen to the fans.
“One time I had a Zoom call from him, when he was in Bangkok and I was in Sheffield, and I must have been with him for two hours and I could only say two sentences to him – he doesn’t listen at all. .
“So, if you were Danny Rohl, and you could see the possibility of him leaving Southampton, then it would seem like an attractive proposition. But I hope we can keep him, because he is a good manager.
“The club is ready for the Premier League too. You can get about 40,000 people in Hillsborough, and we fill it regularly – even when we’ve been in the third tier.
“We are a great proposition for someone, we just need an owner who is ambitious.”
Chris Sutton and Jon McClure were speaking to BBC Sport’s Chris Bevan.
