The 29-year-old is currently in Russia at the World Cup preparing for the quarter-final clash with Belgium on Friday evening.
But Willian continues to be linked with Barcelona.
And Spanish outlet Don Balon, known for their bold and outlandish transfer claims, say Lionel Messi has approved a raid for the Chelsea winger.
That’s after hearing praise from his Barcelona team-mates Philippe Coutinho and Neymar.
The reports also claim the Catalan club have already made a £44m (€50m) offer for Willian.
