Apparently had a fall out with their DoF and
@Zatara said that basically all the signings he demanded have been flops or something this season
However, Bobble was saying last night that basically there's been a few PL clubs unsure on Kovac because it's not exactly clear why he fell out with Monaco's hiarachy. Paul Mitchell is well respected and has done a good job there.
It is however, well known from his time at Bayern, that Kovac can be a very divisive character.
I do get the comparisons to Benitez in how his teams play football. He is however a more modernised version more in touch with football in 2022.
