Just now finished watching the game, hence the belated comments.
Villa are a very tough side. And unfortunately, due to injuries, we didn't have an obvious player to start at DM (presumably Nico Gonzalez was deemed not ready to start). Hence our midfield was vulnerable - and too, we for some reason didn't start Doku, which meant that or offence wasn't nearly as good as it could have been.
I thought that much of the game was 50-50 in terms of which side was best until roughly the 60 minute mark when we brought on Nico Gonzalez, Doku and Nico O'Reilly - at which point we were by far better. I wish that Gonzalez, Doku and O'Reilly would have started (perhaps bringing Gonzalez off at half-time if medical staff thought that this was best).
