The Blues snapped up the ex-Everton man for £15m last week and he is already being lined up to make his first start in the FA Cup clash with Norwich on January 17.
Barkley took part in his first training sessions this week, and Chelsea cameras snapped all the action.
One particular moment went down very well with fans.
The England international was thrown a ball by a coach to volley at Willy Caballero.
He connected perfectly and fired the shot into the back of the net with his weaker left foot, to cheers from onlookers and team-mates.
