Some clubs change managers regularly and most still don¡¯t get it right.

Aston Villa has had seven in the past six years and has tumbled from Premier League safety to a Championship relegation battle.

On the other hand, in Roman Abramovich¡¯s 14-year watch at Chelsea there have been 12 different managers, though thanks to the billionaire¡¯s backing, Jose Mourinho, Guus Hiddink, Carlo Ancelotti, Roberto di Matteo and Rafa Benitez have brought 13 major honors to Stamford Bridge.
