With respect, it wasn't a simple like for like transition.
We played a completely different way, having Everton on the ball and playing confidently rather under Moyes which a more direct brand of football until the final third.
He changed everything about us, top to bottom, without spending any sort of serious cash.
Your argument is one I never understand. Whilst it is absolutely reasonable to suggest that Martinez ultimately failed to deliver - regardless of any context / mitigating circumstances - it cannot be denied in my opinion that he did a wonderful job in that first season.
Utd away, Arsenal away, Arsenal at home, Newcastle at home.... unbelievable performances which were absolutely no reflection of Moyes' team the season before.
Criticise where fair, absolutely. Credit where credit is due is also important.
