Bristol City's inability to defend set-pieces is far from a secret - just ask Barnsley manager Poya Asbaghi.
It didn't exactly need rocket science to exploit the weakness in Nigel Pearson's side and it took just 10 minutes to score their first corner of the contest through Carlton Morris.
Not even halfway through the first half, it was game over when Barnsley's centre-back stooped in the second from another Amine Bassi cross on the same left side.
