Leicester have launched a £30m bid for Burnley's James Tarkowski.
The Foxes are long-term admirers of the defender and are believed to have made an offer that includes add-ons.
They had two bids of around £30m rejected in January but have returned as Brendan Rodgers looks to improve his defence.
Burnley are understood to want £35m up front, with £10m of add-ons, and Leicester’s opening bid is likely to fall short of the Clarets’ asking price.
Tarkowski would be keen on a move to the King Power Stadium as he looks to improve his England chances.
He is yet to add to the two caps he earned in 2018 and is understood to have been frustrated at being overlooked for the international side.
West Ham has two bids rejected earlier this month but Leicester are now in pole position.
Tarkowski moved to Burnley from Brentford in 2016 and has played 143 times, scoring five goals.
Leicester boss Brendan Rodgers has been vocal about his desire to sign another defender and had been considering St Etienne’s 19-year-old Wesley Fofana.
But Tarkowski has stayed on his list and the Foxes can offer him Europa League football this season.
Rodgers hopes to soon tie up another defender, veteran Jonny Evans, on a new contract.
The Northern Ireland centre-half is expected to be drafted straight back into the side for Sunday's Premier League trip to Manchester City.
The return to fitness of Evans comes as makeshift centre-back Wilfred Ndidi is set to be out for up to three months with an abductor injury which will need surgery.
Evans, 32, has now served a suspension following his sending-off against Manchester United at the end of last season and recovered from a thigh strain picked up while on international duty.
Rodgers is keen for the former United and West Brom defender to remain part of the club’s long-term plans, with his current deal set to expire in the summer of 2021.
"Our intention was to get through to the end of the season then the club and Jonny’s agent would pick it up from there," Rodgers said.
"He is clearly a player I would love to keep here. He has been absolutely brilliant, not just in the games but in training with setting the standards and the mentality.
"I believe the discussion will go on between Jonny’s agent and the club, and hopefully we can find a solution to keeping him here."
