Everton are preparing a move for Roma defender Kostas Manolas this month, according to reports from Sky Italia.
The Greece international has long been linked with a move to the Premier League, with Arsenal, Chelsea and Manchester United all said to be monitoring the centre-back's situation.
Ronald Koeman is a big fan of Manolas, who has made 15 Serie A appearances for Roma this season, and is keen to secure a deal as he continues to build on his inherited defensive unit.
The Everton boss has named Virgil van Dijk as his priority target in the winter window, but the £50 million valuation that Southampton have given him is likely to interrupt any potential bid.
