The Spain international completed a summer move to the Premier League champions from La Liga giants Real Madrid last week.
Morata is the fourth of Chelsea’s summer signings so far and arrives at Stamford Bridge with a big reputation from his spells at Juventus and Real Madrid.
Chelsea were in action in Beijing on Saturday as Antonio Conte’s side gear up for the new Premier League campaign.
Morata’s rival for a first-team place Michy Batshuayi was in fine form after the Belgium international scored twice in a 3-0 win against their bitter rivals Arsenal.
And the Spanish forward celebrated the result on his Instagram page with the above snap to the delight of Chelsea supporters.
Morata scored 15 times in 26 games in La Liga last season although the centre-forward found his first-team opportunities limited.
Chelsea finished seven points clear of their closest title rivals Tottenham Hotspur last season.
Conte has signed Manchester City reserve goalkeeper Willy Caballero, AS Roma defender Antonio Rudiger and AS Monaco midfielder Tiemoue Bakayoko so far this summer.
