According to The Scottish Sun, Everton are keen on Celtic centre back Virgil van Dijk - and manager Roberto Martinez is comfortable with paying £10m for the defender.
Van Dijk, 24, has been a star for Celtic ever since signing from FC Groningen back in 2013, but his impressive displays in Glasgow have now attracted interest.
With Everton unsure over the future of defender John Stones, manager Roberto Martinez may be lining up potential replacements - and van Dijk may be one of those options.
The Scottish Sun report that Everton are lining up a move for the Dutchman, with the player wanting a move to the Premier League.
The report even adds that manager Martinez is aware of Celtic's £10m asking price for van Dijk - and is willing to pay it in order to bring the centre back to Goodison Park.
Much depends on the future of Stones, but Celtic may now be concerned by the prospect of losing their star defender this summer.
What would van Dijk offer Everton?
Stones has earned a reputation for being comfortable bringing the ball out from the back, and van Dijk would certainly be able to fill that role.
The athletic defender has pace and power, as well as technical ability, which helps him start attacks as well as score goals, either from driving forward from the back or getting on the end of set pieces.
Whilst stars of Scottish football such as Jean-Alain Boumsong have struggled in England before, van Dijk has what it takes to succeed at Everton if they do manage to sign him this summer, and would be worth that alleged £10m asking price for the Toffees.
