He's getting a lot of sympathy, unsurprisingly, as he's a thoroughly decent bloke, but Brighton have had a really poor season.
They bought 11 first team players in the summer, have a squad that cost more than Watford, Newcastle or Bournemouth, yet lost over half their games playing poor football. They only stayed up because three other teams were absolutely terrible and even then, only by two points.
He's obviously been great for Brighton, but they tried to push things up a level this season and fell well short.
