Burnley boss Sean Dyche is reluctant to liken Michael Keane with Chelsea defender Gary Cahill.
Former Manchester United defender Keane, who has resurrected his career at Burnley, has the added incentive of comparing himself to England defender Cahill.
"He (Keane) is still a work in progress but he's learned a lot since he's been with us," said Burnley boss Sean Dyche, a former centre-half himself.
"I think Cahill's biggest breakthrough was that he learned a lot from John Terry who had that thirst to defend. I think Keano has improved with that thirst to defend because he can play.
"It's something in football to find defenders who actually want to defend and that's the growth in Keano I've been impressed with. I think the balance in his game is getting better, then it's consistency on top of that."
