Look I'm not a Martinez fan or such, but I also believe he is a good enough coach. He is just completely useless in buying players. He would do better in the continental system; where the manager just coaches and somebody else buys the players - technical director or such.
I agree with
@Ashtonian he has a clear idea. A bit inflexible though; sometimes tries to play his kind of game with players who don't have the quality for it.
I also believe nobody can deny, that at least he tried to play offensive football. Nowadays it's boring. For me it's sometimes more fun to lose or draw but see 8 goals.
His interviews have changed a bit to my surprise. He criticizes players after the match. Less phenomenal - thank god for this.
The one thing that landed him some stick with the Belgian press was the fact that doesn't communicate clearly. The Naingollan-saga. First he told the press that he was injured. The player responded in the press that this wasn't the case; so he had to come clean and say it was for disciplinary reasons. Also he became visibly nervous when the press told him they were favourites. He doesn't like that position; so he kept saying that Estonia is a very good team. Should be careful with this. The FA is trying to remedy this by appointing an extra communications officer and sending him to some training.
I agree with
@davek . Hate is a very strong emotion for such things. Didn't work out, he tried his very best - no hard feelings. You wish him well; and continue. Wishing mishap is bad form.
