#5 17-year-old Callum Hudson-Odoi a star in the making
The Blues no. 20 has blistering pace, and he put it to good effect throughout the International Champions Cup clash, giving Arsenal's defence a torrid time - it was he who earned the first penalty. Hudson -Odoi got in behind the cover many times and could have scored approaching the end of the opening half, but his effort was denied by a combination of Petr Cech and Shkodran Mustaf.
It wasn't just his sheer speed that caught the eye, either, as he looked composed when he cut in from the flanks or found himself through on goal, dribbling his way in meandering fashion through an often static Gunners rearguard.
He wasn't fortunate enough to get on the score-sheet in normal time, but if he gets regular minutes under Sarri (something the manager all but confirmed after the game), then the likes of Cesc Fabregas, Jorginho and company will have a pacy wide-lying target man to stroke deadly through-balls to.
Hudson-Odoi is certainly one to watch.
