Agreed, we need another kind, modest man who never talks rubbish about
referees or
UEFA, would never
attack someone else near their eye area and never creates any controversy, another man like Ferguson.
Does it really though? There are one or two examples of it, but I'd say the majority of managers are more successful at the start of their career at any given club than in the subsequent years. Take Wenger at Arsenal, he's been there nearly 15 years now, having success early on, and now they get worse and worse every season, Benitez at Liverpool, won the European Cup and FA Cup in his first two seasons, won feck all from then until his sacking.
Successful managers tend to spend longer at their clubs, yeah, but the success is the causal factor, it makes them more difficult to get rid of, it's not the result.
