I'm really impressed with what I've seen so far, but I think some are getting a bit carried away. He's got us passing quicker and got some actual running off the ball happening with the forwards. We are pressing in a reasonable way but we will still potentially be found out by better teams.
That's why I'm not getting carried away, because Erik has managed to get across probably the simplest pattern of play he had in his armoury. What I understand he was able to do with his Ajax team was to be able to adopt 3 or 4 different formations within a game to keep the opponents guessing and vary his approach.
We might be lucky and it may take a while before a team figures us out, or it could be the first week if we are unlucky. Either way it's important to keep in perspective any early defeats or setbacks. Right now I'll settle for good spells of play, good interactions and levels of intensity and effort from the team. If those can continue and grow then we will get somewhere.
My only other concern is the fragility of mindset of some of these players who have shown promise under Erik but been very inconsistent before....eg Martial, Rashford etc. I hope they can maintain that in adversity as well as when receiving praise.
