Pretty much this. Their second goal was the turning point and it was all of our own making. Dunk's pass to Caicedo was pointless, and put him under pressure.
The usual story against teams that defend deep. We don’t have enough up front to break teams like that down. But that second Forest goal was a disaster. Dunk didn’t need to make the pass, he put Caicedo under pressure, and Colwill was wrong-footed.
