You are using the theory that AVB should not be considered as a potential manager of Everton as he flopped at Chelsea and Spurs. My response was that you can not apply that theory as Ranieri has flopped in many jobs and is just about to win the premier league, it's not hard to figure out lad.
In any case, he missed out on CL football by a point on the last day of the season at Spurs so was very close to something decent which you can't actually class as struggling so your original statement was incorrect for that reason also.
