Burnley boss Sean Dyche is desperate not to lose James Tarkowski this month.
The defender has been linked with Arsenal in recent days.
Tarkowski has performed well since the summer departure of Michael Keane to Everton and is attracting admiring glances from some of the country's elite clubs.
Given the world record price tag on Virgil van Dijk's head, how much would it take to prise the 25–year-old away from Turf Moor?
"£900 million," said Dyche with a smile, before delivering further evidence of his art for making things simple.
"It's no different to houses," he explained. "You've got your house and someone down the road sells theirs for £100,000 more than you thought yours was worth.
"When you then put yours up, you don't put it on for £100,000 less, do you? It's just the business side of football."
