A shame, had a real passion for the game and for the club, but seems not all the players took to him. Did seem to be a short-term fix last season to get us out of a hole, so was surprised he stayed on. The 'resignation' seems more like leave on good terms or you're going!!
As for who's next, does seem to be out of Galli and Oscar Garcia. Might have to ask my Brighton-supporting friend of what he was like. I would like to see Gibbs come back in, in some capacity since he left his role...
If we want to keep the 3-5-2, then maybe Hoddle. Rate him as a coach, and think he'd demand that respect, but can't see it
