He didn't have too many chances to be fair. Keeper made a couple of good saves on him which he couldn't have done much more on.
Frustrating thing is that he made numerous runs to get open (particularly in the first half) and nobody played the ball. Even his offside goal, Arthur takes too long to play that pass.
The bad angle chance in tight, he made a perfect control and the only finish he could, keeper just had come out and made himself big and made a super nice save. That was great from Morata, just even greater from the keeper.
The header was a decent one, and with some luck and mediocre keeping he might have scored it, but he should have done far better and put it out of reach, there was plenty of net to aim at.
The pullback chance he fluffed from just outside the top of the box, he should have got more power on that shot, but he isn’t really a sniper from outside the box, and that’s at best a 1-in-3 type finish for any striker. Anyways, his attempt was particularly poor though.
His control and finish on the pass from Arthur was absolutely sublime, but just offside. he called for it, started to make his run, even tried to hold up with a stutter step, but Arthur took too long to initiate that pass. And it was the only ball of that sort attempted even though he was constantly making such runs.
He also put in a very nice cross for Mckennie, who got nothing on the free header and nodded it straight to the keeper.
All the same, his header and Ronaldo’s header both should have been buried and they both deserve criticism for failing to do so.
