6. Ole Gunnar Solskjaer
The former Manchester United striker has made a great start to his career in managament, and was always talked up by Ferguson as having a managerial mind. He has already been groomed by the club to some extent, after a successful spell with their reserve side, and he has won two titles in his native Norway with Molde FK. It may be a bit soon for the 40-year-old, but he’s surely one who will be considered, and don’t be surprised to see him back at Old Trafford at some point in the future.
