It has always been thus with football managers.
It is the only job in the world where the rewards for failing are usually greater than the rewards for success.
A manager has a ten or fifteen year spell in his career where no matter how much he screws up at one club, there is another one ready to give him a new gig.
And this after a very generous pay out from the club which fired him.
Look at some other examples at the moment.
This time last year Jose was totally screwing up Chelsea's season and dragging the club's name (further if it were possible) through the mud at Chelsea.
Look at him now.
And his previous sacking at Chelsea saw him falling upwards toward Inter Milan and Real Madrid.
Fat Sam was laughed out of Hammers two years ago.....he is now England manager.
Pulis, Hughes, Pardew et al, on a cash laden merry go round which sees them continually getting up on another horse after being knocked on the one they were already on
