None of them are right, none at all.
Marchisio wasn't signed and isn't even playing LM
Asa isn't playing LB, but LWB, which is different.
And Maronne? Wasn't it Conte who thinks he should play there, as a sweeper mind you, not a CB.
Conte will only make an optimal use of the available material he has at hand, it his fault that Marotta has failed to get the players he asked.
Conte must improvise and go with the least compromise, still compromises, but there is nothing else he can do,
he has even admitted that even the selection of the formation was a compromise because of the lack of tools he has asked.
I admire him for that, it is IMO Conte's greatest strength, he is open minded and can adapt the situation to his terms.
But still, that doesnt means that we should accept the root of those compromises for ever.
Since Marotta has been proved time and time again to be such a handicap to Conte's plans and he is holding us back, by avoiding Conte to reach his optimal potential,
then the wisest move would be to upgrade him with a competent transfer manager.
