Think a lot of that had to do with Bartley going off. His physical presence in midfield, breaking up a lot means our defence don't have to get involved as much. Keaghs will chase and battle but not quite the same as Bartley who has strolled 90% of games for us. Perhaps Crawford would have been a more suitable option as someone who is willing to put his foot on the ball and carry it. I'm a big fan of Keaghs and I understand what I'm about to criticise actually got us the second goal but he has a tendancy to just turn and whack a ball forward regardless of there being team mates making runs or not.
I'd also like to add....Menga still looks completely clueless positionally but what an out ball! Him and Dykes is a frightening prospect for any defence.
