The stats are accurate though albeit on a very small sample of games, we need at least another 6-8 matches before I think you could read a style narrative into us or any of team in the league.
I don't think the overall lack of aggression is a weakness. We are high possession so tackling is less necessary but I also think we have taken a conscious decision to avoid giving away unnecessary free kicks because set pieces are probably where we see most threat. I think the tweak is that we have took that to the extreme and been too complacent in allowing teams to get at us and get cross in without challenge.
