Facing frustration in their pursuit of Liverpool ace Philippe Coutinho and Borussia Dortmund attacker Ousmane Dembele, Barca are now exploring alternatives.
France Football says their search has led to Willian, with Barca already making contact with Chelsea about a price for the Brazil international.
The midfielder revealed he was the subject of an approach from Manchester United earlier this year, but chose to stay in London.
Upon learning of Barca’s sale of Neymar to PSG, Willian remarked: “The arrival of Neymar is only positive, the future of this team with Neymar is good. The whole club is very happy to play with Neymar on the team.”
