He's in the process of completing the A badge now isn't he, not sure what he needs to do to get but he's on the pathway
I was under the impression he doesn't have any livences. Usually coaches need to do the C, B then A. Although you can get dispensation to C (and I think B) if you have represented you country.
Pretty sure that if all club agreement, a non-qualified coach is able to take the role. Pretty sure Kosimina doesn't have A, and hence why Trani took them during the ACL.
Did he not go to the UK last off season to do UEFA B?
His Wikipedia page says he holds UEFA B
