Fair enough do you reckon moyes would get the best out of the squad now ?
I think if you look at the statements from Martinez he's correct on 2 counts:
A-- The value of the squad is greater than hes spent
B-- Hes really had minimal investment
Bar Niasse I think you can put his signings into several categories:
1-- Cheap punts
2-- Free signings
3-- Short term stopgaps
4-- Long term signings
Until the Niasse signing his (4) long term signings were Lukaku,Mori,McCarthy,Deulofeu Besic, Galloway for money.
I think based upon that he would have made an ideal director of football given funds to spend ONLY on that category of player.
To answer your question on Moyes its really hard to gauge how he would line up the team. I dont think Mori or Stones would get regular games under him if he had other Jagielka ultra defensive type options, also Deulofeu and Lukaku and Barkley would likely suffer under him.
I think he would be a failure at getting the best out of this squad, we need a manager who is adept tactically to play attacking football like De Boer OR someone like Mourinho who can bring in players to improve the quality of the team.
Moyes was good at getting the best out of limited players to improve the team.
