Chelsea have rejected Barcelona's proposal of Malcom plus cash for Willian.
The Stamford Bridge club want straight cash for the 30-year old, who is interested in the move.
The Spanish side were willing to offer Brazilian winger Malcom plus cash for Willian who saw a proposed move to Barcelona fall through last year.
Malcom cost £38million from Bordeaux last summer but has failed to live up to his potential and is being courted by clubs across Europe.
Barcelona bought the 21-year-old after being rebuffed three times in their efforts to prise Willian from Chelsea.
Chelsea rejected offers going up to £65m in July but as Willian has turned 30 and has only 18 months left on contract, they could be tempted with a cash offer of £50m in this window.
