I don't think Brozovic is really a DM, I think he can play there but not sure it is his best position.
But even it was I think that statement is a problem if true, especially if you around at what we have. Brozovic should not be the best DM we have, if he is that is not a positive about him but a negative about how poor our roster is.
I am not saying we can get any of them but look at some on the other names in regards to Inter that have been talked about in MF, Barella and Tonelli. Both are so much better than him, Those are the level of players we should go after, the kind that Inter is reportedly keeping and reportedly using to replace Brozovic.
Maybe I am overrating we where are in the footballing world but I am not sure we should be happy that we get Inters scraps and now make them starters. I am hoping that we have more ambition than that. Inter is a good club but we are not talking Bayern, RM, Barca or City here. It is a club that we should be matching ambition with I would say.
I think what I bolded is partially the problem. We aren't a club that spends big money. I really don't want to rehash the never ending argument of whether or not we should be a club that spends more. The fact is, we haven't been previously, and we won't be in the near future.
With that said, we'd be swapping out a position-less player for a guy that'd be filling a massive need, and is better than the player we'd be giving up. As far as the other names you brought up, sure, I'd be happy with them. But we may even get the chance to buy them. It's definitely more complicated than "we need a DM, he's a good DM, let's buy him". And I know that's not what you're saying, but Tonali is a good example. He is a young Italian player who everyone says is going to be a star. Would be a fantastic player to sign. However, all the big Italian clubs want him. Chances of luring him away are slim.
TL;DR....Brozovic is an upgrade and if we could potentially get him for a steal there should be no hesitation unless there is a personality or work ethic issue.
