Well they scored 9 of their 10 shots on target the last two matches and of 20 overall shots. Seems they either have definitely hit on a way to guarantee goals or they have just been lucky to play two leaky defences.
A few weeks' ago, Forest fans were complaining that they were having 15-20 goals-attempts and not scoring; presumably they had a high xG. Now, performance vs the xG is normalising as they are scoring more freely.
However, the Blunderland game was a bit 'out there' in that the home side massively underperformed vs their home-form trend.
Forest will have renewed confidence against us, and that can be a pretty powerful plus: we have to ensure that we are not bullied or over-run early in the game; make it tight and force them onto the back foot. If we serially concede possession and appear uncertain in our gameplay, they'll beat us.
