The Sun says Barca are in talks to launch a £50m player-plus cash bid for Willian.
The Spanish giants are prepared to part with La Liga flop Malcom plus a multi-million sum in order to try and land the Blues' Brazilian winger.
Barca signed Malcom last summer for £38m from Bordeaux after they had THREE bids for Willian turned down, including one for £65m back in July.
But Malcom, 21, is now thought to have missed his chance at a first team breakthrough after a stuttering start.
And Willian, 30, is thought to still be the answer at the fourth time of asking — despite his senior years.
