In Arsenal's 4-0 Europa League win over Slavia Prague in April, Bukayo Saka tormented the opposition left back so much that he needed substituting after 45 minutes.
That was Jan Boril, the experienced Czech Republic international who had the sorry job of trying to tie down Saka on Tuesday night all over again. There was only ever going to be one winner in that scenario, and it was the England starlet.
Saka was involved in the build-up to the opening goal, switching play from the right to the left before Jack Grealish crossed and Raheem Sterling scored.
