Three standout managers this year. Motta, Alonso and McKenna.
Three other managers that have had impressive campaigns this season.
Sebastian Hoeneß - Stuttgart were relegation candidates when he took over. This season, they were Bayern Leverkusen's most difficult opponent failing to beat them twice in three matchups, with Leverkusen's goalkeeper being their best player in one of them. Hoeneß side are possession oriented like two of the three managers you mentioned.
Eric Roy - With him at the helm, Brest have reached the Champions League qualifiers stage for the first time in their history, and may skip the qualifiers altogether if they win tomorrow and Lille drop points to Nice. They were relegation candidates last season. Unlike with Stuttgart, I haven't seen much of Brest in action and can't comment on their style of play.
Míchel Sánchez - Girona were languishing in the second division when he took over in 2021. Fast forward to this season beat Barcelona home and away, whilst at the timing of this message only Real Madrid have scored more goals, secured Champions League football, and I think it wasn't until February when Real Madrid ousted them from the 1st spot.

If there's truth to Motta joining Juventus, I would be rather curious to see if he an get his ideas come across. Would hate to see a repeat of Maurizio Sarri's spell with Juve. There was expectation for him to have a galvanising influence on their style of play and it didn't quite happen. And will be interesting if Motta can have a flourishing relationship with the Juve hierarchy, in a similar vein to Bologna's Marco Di Vaio and Giovanni Sartori. Conversely, I've enjoyed Juventus' suffering in recent years, and I'd rather Motta joined a Bayern Munich or a Barcelona, than to attempt to revive Juventus.
