Burnley boss Sean Dyche knows Michael Keane is attracting big club interest.
Dyche is focusing on getting the best out of his central defender for now rather than looking too far ahead.
“It's a double-edged sword," he told the Lancashire Evening Telegraph. “It's a compliment in many ways that people are writing stories about your players but there is a challenge to make sure we, as a club, are secure.
“We said in the summer that players weren't for sale and they weren't. Keano's still here. We don't worry too much about the future."
