Willian has in the past been linked with a move to Stamford Bridge and Tottenham Hotspur and he remains keen to one day make a move to a big club.
"I'm very happy with my moment at the club and I intend to keep living this moment," he told Globo Esporte.
"As for a possible transfer, there will be offers for sure and I work so that it happens.
"My club and my representatives will decide my future. I'm focused on helping Shakhtar to keep making history in the Champions League."
