For me the issue with Zegrova is that he is on the same level as Chico; ie no upgrade over what we already have. Obviously this wouldn’t be a problem if they were both starting materials, but unfortunately both of them are only bench players in my eyes. To bad we don’t have money to buy anything better.
Secondly, if both Kostic and Vlahovic end up staying, his arrival could pose issues within the team. Although, both kostic and vlahovic look like absolute soy boys and everything would probably be just fine. I wouldn’t expect the same with Mitrovic on the team for example.
