Ben Marshall is hoping some of Leicester's magic can rub off on Blackburn when they face West Ham in the FA Cup fifth round on Sunday.
Marshall left the Foxes to join Rovers two and a half years ago and has watched on in amazement at the achievements of his former club.
The 24-year-old winger played with the likes of Jamie Vardy and Danny Drinkwater, and has backed his mates to lift the Premier League title.
He said: "I do [think they'll win it]. I keep in touch with a few of the lads and I think they're quite confident.
"I'm quite close to Danny Drinkwater. He's doing well and there's talk of him getting an England call-up, so I wish him all the best and hopefully he can get a Premier League title next to his name.
"When I left obviously they were still in the Championship so they've come on a lot. It's nice to watch them play and see them doing well."
While a Blackburn win over West Ham would hardly cause the same ripples that Leicester have done, it would put Rovers into the quarter-finals for the second year in a row.
Last season they took Liverpool to a replay before exiting, and Marshall believes Championship sides should take inspiration from the Foxes' exploits.
He said: "Anyone watching, especially Vardy's story, it gives you a bit of hope and it's good for the teams who will go up this year. Not just trying to stay in the league but maybe pushing on to try and win it.
"Leicester have achieved the impossible. They're up there and the more games they keep winning the closer they get. Hopefully we can take a bit of that into Sunday's game."
