Gasp is a coach and in this business, you are paid to get results regardless of the situation. You are not paid to showcase what you know/think you know or to showcase your idealism. You are paid to get results! FFS, that is why he was fired from Genoa in the first place
Maybe MM and Branca are at fault for making the assumption that Gasp is smart enough to know this already (like they did with Rafa, who proved he wasn't smart enough). Either way, this is the coaching business and Gasp should know this. I cannot think of a single top level coach who's coached different teams but always used the exact same formation/tactical setup.
Of course MM is getting frustrated because things are looking like fuckin deja vu. We had Jose who found the right balance between defense, midfield, and attack. Then we got Rafa who was obsessed with midfield (possession) but was impotent on defense and toothless in attack. Then we got Leo who was terrible at defense, but controlled matches in midfield and was ultra creative in attack.
Now, so far, it seems Gasp is obsessed with midfield (possession) just like rafa, and is sacrificing defensive stability (backbone of Inter) and offensive quality. Almost all preseason games have a similar feature to it, no matter what "tactics" are employed:
(1) Extremely fragile defense. Way too open/exposed. Opponents getting several opportunities on goal
(2) Ridiculously toothless attack. We're hardly creating shit in attack. Similar to rafa days, we are struggling to get BEHIND defenses.
The jury is still out on Gasp as he is still tinkering and learning the characteristics of our players. How he fares near October will be more indicative of his level of intelligence.
And I don't want to hear shit about getting the players he wants. He should not get the players he wants. You have to prove you can manage the squad, the expectations, the high pressure e.t.c., before you can earn that type of trust. All good coaches can make do with what they have. Think about national team coaches. They don't have a fucking choice. They have to manage what they have.
