I'm saying Higuain did not create that goal, he kept the ball in play, Mandžukič didn't have a goalscoring opportunity, he scored from a position that no one is going to score from regularly. Yeah it is an assist technically, but in reality he didn't create that goal, Mandžukič created and scored all by himself.
In the case of Tevez, without that "missed shot" as you like to call it, Morata wouldn't get a chance to tap it in a free net, that goal was 80% Tevez and 20% Morata being in the right spot at the right time. Tevez didn't have a good game 2 years ago, but he wasn't half as useless as Gonzalo was in the 2nd half. What's the point of having a big and relatively slow CF if he can't protect the ball? Higuain did literally nothing positive in the 2nd half, couldn't keep the ball, couldn't press defenders, didn't make any runs for our passers to pick out. Anyone capable of running would've had a bigger impact on the game in the 2nd half.
