Chelsea are in talks to sign Colombia winger Juan Cuadrado from Serie A club Fiorentina, according to Sky sources.
The 26-year-old impressed at last summer's World Cup and has a £26.8m release clause in his contract at the Stadio Artemio Franchi.
It is understood that no formal offer has been made by Chelsea, although there has been speculation that the Premier League leaders had an initial £20.6m bid rejected on Wednesday.
There are also reports that Cuadrado's agent, Alessandro Lucci, is set to fly to London with a view to brokering a deal.
Blues boss Jose Mourinho looks increasingly likely to offload two of his current wingers as he waits for improved offers for Mohamed Salah and Andre Schurrle from Roma and Wolfsburg respectively.
Cuadrado, who along with Germany star Toni Kroos led World Cup 2014 in assists, initially joined the Viola on a season-long loan from Udinese in 2012 - impressing sufficiently to earn a permanent switch the following summer.
Since arriving in Florence, Cuadrado has racked up 21 goals in his 82 appearances for the club.
He was on target on Wednesday with a 12th-minute penalty as Fiorentina beat Atalanta 3-1 in the Italian Cup.
