Difference is I think Ron could change if he feels confident enough in the team and formation but that's partly down to him. Mitigating factors today is the ammount of games in one week plus we have injuries and lack of that focal point. If we get everyone back and the signings in and it's still the same set up then it's time to make a judgement. What I like about Koeman is that he isn't afraid to change formation or personnel within a gane if he gets it wrong, hopefully he recognises we need to carry more threat away from home, especially against the biggest teams you can't just sit in and hope for the best everyone, three at the back can work with the right players but if you just sit in against these teams 9/10 times you will lose, that's mentality, players and tactics.
