To be fair, the things that went wrong at Leicester couldn't be fixed in a week. We played well for 45 minutes at Leicester, and about 70 minutes against Arsenal. We should be able to pull off a full game against Chelsea (!!!). Fitness isn't a quick fix.
I am wondering if, with Bobby only being a young footy manager at 41, this would have been his first experience of having several players away at a world cup. The approach in pre season maybe reflects this. Low key, strange player choices, not many games etc. I guess there has to be a right balance between rest and intensity. I have no idea how they would figure out the best way...but I am sure that Bobby has analysed it all and probably, hopefully, learnt from it and be a better manager for it. To our advantage.
We'll be in full swing within a couple of games and will all be making cyber love again on this forum.
