Depends how narrow you want to judge the job he's done imo. Seeing the final table we were safe with 5 games to go, that in itself is marvellous from where he took over, particularly without a centre forward.
If you take a broader perspective you see a winning pattern at home which is unsustainable, (not his fault),a series of lines ups away from home which set us up to fail, resulting in more half time substitutions I've seen from any manager, questionable man management skills, doesn’t play the player he specifically wanted and we are paying way over the odds for in as many games as he does, a team who have had no pride in at least 2 away performances leading to our heaviest defeats since coming up and his post match stuff about not being to re-sign Costa and Adama tipped him over the line for me of playing the media game to just looking petulant.
I want him here next season because he's only going to be so if he's convinced by the investment and I have no confidence in us recruiting someone on a par or better. However I'm not as sold on him as others are.
