The 47-year-old is currently priced at 2/1 by SkyBet, with his nearest rival – Manchester United academy coach Nicky Butt – priced at 5/2.
Ainsworth himself has now spoken out on the speculation, and his comments are coy to say the least.
Speaking on Sky Sports News, he said: "[Wycombe and Preston are] Two fantastic football clubs, that is all I can say.
"I'm flattered as always to be linked with these jobs. I started my career at Preston which holds a big piece of my heart.
"As I have always said, it would take something super special for me to vacate Wycombe where we have built that culture and what we have done so far.
"So there will be no comment from me."
Wycombe have endured a tough campaign in their first ever season in the Championship, and are currently rooted to the foot of the table having won six games out of 38.
Ainsworth himself remains a huge favourite at the club, however, and has overseen around 450 games in the dugout for Wanderers.
Elsewhere, pundit Gabby Agbonlahor has poured cold water on the prospect of Alex Neil taking over as Celtic manager.
The 39-year-old was given the boot by North End recently, and the Hoops are still on the lookout for their next permanent boss after parting company with Neil Lennon.
But speaking to Football Insider, the ex-Aston Villa man quashed any prospects of a stunning move to Parkhead.
He said: “I don’t think that Celtic are going to make a massive decision like this and give it to someone who has just been sacked by a Championship club.
“I just can’t see it, to be honest.
“They’ll be looking at someone who has had a better career than Neil, to be honest.
“I don’t think they’ll be looking at him – no way.”
Celtic legend Chris Sutton recently touted Neil for the role during an interview with the Daily Record, while the Daily Mail suggest that the Hoops have been interested in the manager since as far back as 2019.
