Not sure how you can compare a preventable goal to a unpreventable goal and also, if we were conceding a lot of 30 yard screamers, we would say 'we should start closing the opposition down' rather than just accepting the pattern.
I get your point and it was undoubtedly a good header. However, it was preventible.
Also, we can't say 'we only conceded because of brilliant movement and a pinpoint cross'. It's the Premier League, that should be expected.
