#10. Gary Neville
When you’re thinking about what would be the ideal job for your first foray i to management, it’s probably not advisable to go into a struggling club in a foreign country where none of the players speak the same language as you do. Gary Nevile was a huge failure at Valencia and it was a poor career move. He may go into management again in the future but now he has a reputation that he’ll need to put right. In the future could well find his way off his list, but for now he ranks as an unsuccessful manager until proven otherwise.
