Callum Hudson-Odoi celebrated in the corner of Stamford Bridge with old friend and opening goalscorer Trevoh Chalobah after putting Chelsea 3-0 up against Juventus.
Not many people realised that the pair have been in exactly the same situation around four-and-a-half years before Tuesday night's triumph.
