Around the video’s 1min mark, after Juan made that tackle Rano was tracking Bianchi, the no 9 while Cambiasso and Juan both lost Sgrigna, no 10. A dangerous cross came in and Rano, realizing that 10 was unmarked for a free header, left his man no 9 and leapt to challenge, denying what was a certain goal. You can see that Rano was angry (a swing of the arm) and eyed Cambiasso (who was partly at fault). That 5 seconds sequence of play shows a lot about Rano’s maturity as a CB.
