Willian already proved himself last season, yes he can improve but he didn't have a bad season at all. Whenever he was on the pitch, you could see Hazard had less pressure. Willian can dribble and beat 2-3 man, keep the ball well and is very good in counter attacks. He wasn't super productive, just 4 goals but he does more than goals. He recovers balls, gives many keypasses, defends well and is one of the best high pressing attacking mids we have. Hazard, Willian, Schurrle are the 3 starters for me this season. A combination of creativity, goals, super pace and high work rate.
