Tbf I was struggling to find a stream so I might have missed a few bits, I saw one time they break through and Ospina could have conceded a pel although I don't think he touched him and it would have been harsh.
The BBC says they had 16 shots but only one on target which does sound like they were pretty erratic and should have scored more, from actually watching the game though it didn't feel like that.
We seemed to pretty much be controlling the game. They could have scored a couple of goals, we could have scored more too though.
Overall the assertion that they could and should have hammered is, as I may have intimated, bullshit.
