You can't have it all ways
Any criticism of Ole always uses his own record as a manager against him (Cardiff) but ignores Molde.
Lampard did manage Derby so he is not a complete novice
Arteta is fresh and new but the criticism of him as being a novice for such a large club is valid.
Lampard, Ole and Arteta are managing high status clubs and as much as you want a bespoke assessment and can do this, ultimately the status of all 3 clubs weighs heavily.
F-w-i-w, Lampard has done ok but should be slightly better in play consistency and league performance. If current performance dips could be shown the door. His current team selection and tactics are worrying. His midfield is weak.
Ole has done well but still lacks consistency in defence, certain attacking phases, squad rotation and crunch cup/league games
Arteta started incredibly but this season, even with injuries, is performing very poorly.
Let's see where they end up this season.
