The Europa league is the third in line after the champions league and the league title of a major footballing nation. Mourinho has had a successful season, champions league qualification as well, easily surpassing Pep.
Sets things nicely up for next season - Chelsea (Conte) Utd (Mourinho) City (Pep ) teams with the top resources with highly decorated managers with varying approaches to the game, Liverpool (Klopp) and Spurs (Pochettino) lesser resources, good managers who have to give that bit extra to their teams to get them challenging up there, Arsenal (Wenger) tbc, Newcastle (Benitez), top manager first season back, you don't expect them to be challenging up there but he will build a team that will be competitive against every one of those top sides, I would include Koeman and Everton in the list but they don't really seem to have a direction.
A great collection of top managers, varying approaches, teams with money who can scout the world, so much scope for improvement if you get the scouting and tactics right.
