There are so many "roundabout" managers with failure after failure yet still find themselves in a job too often so not sure I agree
He was under very little pressure at Swansea. He had the support of the fans and had managed to cut the wage bill significantly whilst still producing a decent outcome. At Brighton, he'll be under huge pressure to deliver, the Premier League is a very unforgiving league and Brighton's squad is very limited at this moment (who knows what sort of budget he'll get)
The chances of him getting sacked are a lot more likely at Brighton than at Swansea. Surely he'd prefer to earn a "lower wage" than be unemployed
Earn a high wage and be successful = moving on to better.
Earn a high wage and get sacked in six months with a massive pay off then get another job.
Earn a lower salary and maybe get sacked in six months anyway.
Stay at Swansea, continue building a decent reputation, and maybe take them to the Premier League where they would pay him a higher salary anyway
Which is a far less likely scenario. I hope you’re not a gambling man URZZZZ.
