For the sake of argument I have left out Leandro, this due to the fact that he has twice been interim manager! First at Milan, then Inter.
I don't get everyone being so critical of Abramovic sacking Ancelotti and using Man Utd as a template! Ferguson is NOT the rule, but the EXCEPTION!!! Look at Wenger, he created this incredible team, buying players that fit, with leadership right through its very core! After that era ended, Wenger has become comfortable enough in his job in order to try and create a perfect footballing machine, and he has failed! On the other hand, Mourinho, Guardiola, Mancini, Redknapp, Dalglish, Ancelotti and Allegri are arguably the managers for the biggest teams in Europe not including Manure and Arsenal (obviously Carlo has gone but for the sake of argument)! How long have these managers been at their respective teams?
AND If you don't believe that these managers have had tenures at all their clubs for an average of;
Mourinho - 1.8 years
Guardiola - 2 years
Mancini - 2.25 years
Redknapp - 4.4 years
Dalglish - 2.4 years
Ancelotti - 2.8 years
Allegri - 1.17 years
These managers on the most part have been successful enough to be deemed worthy of their job, yet only Redknapp has averaged more than 3 years per managerial post!
Yet between them these men have won on average 6.86 trophies between them!
So is it over-rated?
