According to the Daily Mirror, Leicester will look to sign the £20-million-rated Aston Villa midfielder if the Villans fail to gain promotion this season.
Steve Bruce's side are guaranteed a play-off place, but trail second place Cardiff City by four points having played a game more.
And Grealish - who missed a chunk of the campaign through injury - is a man in form, scoring two goals and creating another in his last three appearances.
But what do the fans make of the speculation? Here's the lowdown from both camps, starting with Leicester's...
I really don’t want Grealish at Leicester not because of his “attitude” problem but because he’s the most overrated player I’ve ever seen. Lloyd dyer has two less goals and assists than him in the championship this season and he plays for bottom of the league burton!— Lennon Veasey (@Foxyproxy1313) April 17, 2018
James Maddison > Jack Grealish I hope we go for Maddison— Timmo (@WorldclassWes) April 17, 2018
Get shaqiri please— James Clarke (@Jclarke776James) April 17, 2018
I’ve watched Grealish live about 10 times this season. Trust me, he’s good enough to play behind Vardy.— Ollie (@OllieParsonss) April 17, 2018
Jack Grealish fits all the remit or what Puel needs, young and British also, you can always refer back to the negatives that comes with him.— LCFC_Talk (@the_tfd) April 17, 2018
But you can bet your bottom dollar he’d knuckle down, he’d be in the England squad within 6 months.
I think Grealish would be a decent addition, wouldn’t be that annoyed if we didn’t get him though.— NH (@UB906) April 17, 2018
We don't want average grealish anyway— You Just Looked Here ┌(˘ᴗ˘)ʃ (@Noncedolo) April 17, 2018
Let him go wolves imo
Fella in pub says Jack Grealish is coming to the city. The definition of the quiffy hair nancyboy fancy footballer. Avoid like the plague.— bob (@oldbob1944) April 17, 2018
And this is what the Villans are saying....
Also, I think Villa have every right to demand a ransom for Grealish, who would be worth twice as much if he was playing in another league. Jokers.— 7500 to Holte (@7500toHolte) April 17, 2018
This is my worst nightmare. I think we all accept that if he progress as he should he'll get to good to stay with us but I don't want him leaving for a club like Leicester. When he leaves I want it to be so he can play in Europe— Comrade Grealish fan (@Stokesey84) April 17, 2018
All these people going mad about £20m for Grealish.— Hardiman (@harryhardi_) April 17, 2018
He's got a long way to go but £20m is about fair considering his age and potential.
Can't even blame Grealish if he choses to leave in the summer if we don't go up, far too good for the championship and deserves to be playing at the top level #avfc— . (@CV1874) April 17, 2018
People having a go at the Jorno about the Jack Grealish story, I don't know if this story is true but in my opinion Grealish will not be playing in The Championship next season, neither will Chester, Johnsone or Terry.— Villa Mad (@VillaMad3) April 17, 2018
We certainly won't keep Grealish if we don't go up, or Chester. Those two are about the only two you'd miss if they went— James Speirs (@JamesSpeirs15) April 17, 2018
I must be the only person here who thinks 20-25 million for Grealish if we don't go up to be about right— RJ ⚽️⚾️ (@EvilVillan) April 17, 2018
According to the Daily Mirror, Grealish is likely to stay at Aston Villa - on an improved contract - if he helps his boyhood club back to the Premier League.
The 22-year-old is said to earn £20,000 a week at Villa Park.
Could Grealish leave for Leicester if Villa don't go up?
