He's tactically quite poor, but has been very good in all other aspects of the job IMO.He’s done well with certain parts of the job, he’s a great communicator, for example, but tactically he’s rather challenged compres to some of his peers.
Some people only focus on on-pitch in-game decisions (understandable to an extent, as that's the main thing we see) but I believe he has provided huge value in other areas, and the players recognise and appreciate this.
