Not sure there was much wrong with the formation myself, although why we saw Fernandino going forward and Yaya holding, god himself doesn't know.
And they hardly played us off the park either. Two away goals and better defending and we would have picked up the points.
But I do criticise us for our lack of intensity. Last 5 minutes, when the penny had dropped that we had fucked it right up, we upped the pace, played with urgency and scored easily. We would have gone on to score more but ran out of time. Why oh fucking why did we have to wait 91 minutes to see that response???!!
