Chelsea have reportedly launched a £20m bid for Shakhtar Donetsk midfielder Willian.
Arsenal manager Arsene Wenger tried to bring the Brazilian to the Emirates Stadium last summer after a number of strong performances in the Champions League, according to the Daily Mail.
However, Wenger was believed to have been put off by the asking price for the 23-year-old.
The Blues could end their pursuit of Lille's Eden Hazard if a deal is struck with Shakhtar.
