On one hand, it was a bad miss and he should have scored and on the other hand, it was a good save. Players miss chances all the time, even in big games. The only reason the furore with Werner exists is because of the number of chances he has missed this season.
What other chances to score? His miss and Pulisic's goal were the only real chances we had. I wasn't keeping track of it but saw some point out that had Werner scored his chance, the Pulisic goal might not have happened due to the same sequence of play etc. Will need to go see it again. But that aside, we ruined a lot of promising situations in the first half with poor final passes and in the second half, we created nothing. Can't remember us testing Courtois at all.
There's still another 90 minutes to play. If we get knocked out by Real Madrid, it could be for various reasons. All the talk about Werner's miss and no one has even mentioned about the poor defending that led to Benzema's goal, for example. We should be doing better in attack to render such moments insignificant.
