Clutching at straws a little now, but what about:
Roberto Di Matteo
Pros:
Champions League winner, beating Bayern at their home stadium in the final and also Guardiola's Barcelona over two legs, despite playing most of the second leg with 10 men. FA Cup winner, spanking us 5-1 and beating Liverpool in the final. Attractive, attacking football. Beat us 4-2 at White Hart Lane and beat Arsenal at the Emirates twice (including once with West Brom), and thrashed Napoli 4-1 in the Champions League. Got West Brom promoted and off to their best ever start in the Premiership, playing good football with new signings like Odemwingie. Has quite legitimate cause to say he was badly treated in a transitional season having lost Drogba and trying to integrate new young foreign players like Hazard, Oscar and Azpulicueta into the side. His players all really liked him. Knows the Premier League. Despite his Chelsea connections, is actually a fairly likeable character.
Cons:
Has been sacked after less than a full year in charge in both his Premier League jobs - "no smoke without fire" as they say. Questions asked of his tactical nous and his ability to turn things around when going through a bad spell. Some of his successes were massively down to luck, Barca or Bayern could easily have scored 5 or 6 in all three of those games. Widely considered a "yes man", with no real authority. Chelsea ****.
Neil Lennon
Pros:
Winning anything in Scotland is irrelevant if you're the Celtic manager, but he managed to beat Barcelona in the Champions League last season. Came across really well on MOTD a few weeks ago, well spoken and with good tactical insight. Knows the Premiership.
Cons:
Completely unproven in a competitive league. Issues about his temperament.
