Leicester have had a bid in excess of £25.5m for defender Merih Demiral rejected by Juventus.
The Italian champions are also reported to have turned down an offer of £34m from Borussia Dortmund for the 21-year-old.
Demiral joined Juventus from fellow Serie A side Sassuolo in July but has struggled to make an impact in Turin, playing just five times.
He is predominantly a centre-back but can also play at right-back, and has 12 caps for Turkey.
Leicester have predominantly relied on Jonny Evans and Caglar Soyuncu in the centre of defence this season, with the pair making 49 appearances between them in all competitions.
They have helped the Foxes earn the second-best defensive record in the Premier League, conceding just 19 goals in 21 games.
