That happened because KDB lost a tackle that was at least 80/20 in his favour & that allowed Palace to break. The number of tackles we lost that we should have won was criminal. There was one where Zara had 3 City players around him, all capable of winning the ball, but somehow came away with it unchallenged.
Having got into a winning position with minutes to go, yet again we didn't show the drive or desire to defend that lead. Soriano and Begiristain should be asking the same hard questions of Pep that Cook & Marwood asked of Hughes when his team went through a patch where we couldn't hold onto a lead. And if Pep can't answer those questions satisfactorily then he can have no complaints if he suffers the same fate.
I assume this post is after match anger. It can lead to unrational behaviour.
