Champions Leicester and Chelsea are keen on the £30million-valued centre-back, who has impressed with a series of top-notch displays this season.
Heaton told The Sun: “Keano has been superb and it was no surprise to me when he was linked with some of the top teams.
“He’s done very well. He’s big, strong, quick, good in the air and decent on the ball. There’s not many defenders with those qualities at his age in the Premier League.
“He’s getting great experience but hopefully he’s at Burnley for a long time to come.
“He’s a massive asset to the football club and he’s going from strength to strength.
“When you are playing well there is always speculation – it’s part of football. But we all want him to stay at Burnley.”
