I do think AVB spends more time in making sure game start with damage limitation as opposed to all-out pedal to the metal. And I agree that when it comes to home games, he could've done with a little less caution at times for sure. But I also think that in fairness, some of the games you've mentioned saw some excellent defensive blocks which prevented at the very least a keeper having to earn his corn (Stoke leaps to mind in this regard)...anyway, I agree, a little more bravery at home sometimes would be appreciated, but overall I think we are really starting to see what the man is working towards.
Yup, Rome wasn't built in a day.
My mate who usually watched games together with me, was very upset when we lost at Everton and didn't beat Stoke. He was very happy today. But I think our performances were about on the same par over the last few games. Everton was a solid considering we were playing away to an opponent at about our level.
The playing style will improve when the team is used to it and even better if AVB can get his preferred players this coming transfer window.
