I have noticed a trend that now coaches who have ever worked with Guardiola are highly valued (Kompany - Bayern, Maresca - Chelsea), and if the first one is quite young and has not yet proven his skills with impressive results, then Maresca was able to win the Championship, which looks very earnestly. He is already discussing summer transfers with the management, for now it is reported that he wants to buy a goalkeeper and a defender.
The UEFA zone is quite cramped, especially if we are talking about those who have been in business for many years, I think that it is not the theory of 6 handshakes that works here, but a maximum of one or two handshakes

Now it seems to me better to pay attention to Xabi and the fact that he worked with Mourinho. And by the way, Mourinho said in advance that Xabi has everything to become a good coach.
