They are "supposed" to be the best club side in the world, so with that in mind they'll be looking for the best managers. Jose fits into that criteria with ease and its only natural for him to be considered.
The only downside to him from a Manure point of view is his style of play which Robson and Charlton have mentioned. Judging from Manure fans response about him potentially being their next manager the camp seems to be split. Many see him as too negative and others say he's the ideal person to handle to big egos that float around.
Yeah I'd be gutted, but I wouldnt have any ill feeling toward him. Look at the response Zola got when he returned with West Ham. I'd expect Jose to get the same if it ever came to that. Booing him on returning with a major rival would be idiotic. Romans money aside, he transformed the club and made us a genuine force and hopefully his legacy will carry on for many years.
