The changes are not marked enough to overcome the plethora of issues that are tied to the manager like an anchor.
If you're talking about being objective, then answer these questions objectively:
1. Has his in-game management improved, at all? If yes, in what way(s)? Early days into the season but no
2. Has he shown improvement in 2nd half of games' management? Same as above. Early days, but this season he has the options on bench to make changes that can help us push on to win the game and he has so far failed to do that.
3. Do you think it is finishing alone that would change our season, up 'til now, around? Yes, with better finishing we would have won games against Brighton and Palace and the game against Fulham would have a more convincing scoreline.
4. Is he doing well with the squad at his disposal? No, he can do better
5. Has he outcoached any team outside of the Barnsley game? I'd say he outcoached Brighton, Palace, Fulham, Southampton, even City(if we are taking CS into account). Against, Liverpool we were in the game until 23rd minute where Casemiro went nuclear and after that we didn't deserve anything, even if we had couple of chances. Same story against Twente, controlled the first half fairly well, but didn't do nearly enough to say we deserved a win.
Now if you are being objective, you'll answer these with no spin or self-serving regardless of what that concludes as.
