Chelsea have handed Christian Pulisic a new shirt number.
Chelsea have given Pulisic the club's No10 shirt after Willian moved to London rivals Arsenal, according to reports.
Pulisic enjoyed a strong debut campaign at Stamford Bridge after arriving from Borussia Dortmund, scoring 11 goals and producing 10 assists in 34 matches in all competitions last season.
The Athletic reports the USA international has since been handed the No 10 jersey in west London - which has been worn by many famous names down the years.
Willian joined Arsenal on a free transfer earlier on in the summer window, having spent seven years at Chelsea.
The Brazilian had inherited the No 10 shirt from Eden Hazard before the beginning of last season when the Belgian winger joined Real Madrid in a mega-money deal.
