He wasn't cut out to be manager.
From memory, he was second choice.
But got the gig on the understanding that Bobby Robson would be the senior partner.
Bobby's ill health meant that Stan assumed more responsibility than he was probably ready for, bearing in mind his experience up until that point was a bit of coaching and making the tea at Walsall.
But we are talking about a bloke who earned 120+ caps for his country. I don't blame him for wanting the job. Rather, you'd have to look at the FAI for appointing him.
