Success is a hard one to gauge....you could argue that given the resources he has at his disposal he has already been successful both at everton and previous clubs. Time will tell and his signings key to this story.He hasn't been successful at Everton and to say that already is outrageous.
He shored up a leaky defence and made us hard to beat. Exactly what was expected.
If he can go beyond that and take us up a level then he will have been successful.
Plenty of time left and it's too early to judge him. Hopefully we can have a strong transfer window and strengthen appropriately to give him the best chance of success.
