Brozovic would be alright, better than Witsel and Gustavo in my opinion. Very steady midfielder, can play a variety of positions, a box-to-box threat in the sense that he is quite creative but doesn't neglect his defensive duties. Pluses also include his young age, nationality and weakening Inter lol. He is one of the key men in the current Croatia national team, and starts all games over players like Kovacic.
There are much better options available don't get me wrong, but I'd rather take him than most of the options thrown around. He's nowhere near players like Vidal and Pogba and never will be.
