Agree with your points but Zinch wasn't *the* match changer v Villa. Raz and Kevin contributed great assists, Gundo scored two, and Rodri had to be perfect to score from Zinch's assist, 99% of the PL players wouldn't have scored from there.
To downplay the contributions of Gundogan, Rodri, Kevin and Sterling in order to big up Zinch's impact sems widespread on here but still feels weird. If there's one man who changed the game it was Gundogan. Several players contributed a lot, Zinch was one of them.
