Not that I know anything about it, but I don't think Rafa would be too interested - I can't imagine him being happy not working on the "project" he keeps talking about where he's working with the same team week-in, week-out. Also, after the time he had in the RM job I wouldn't imagine he's too highly regarded by the RM/Barca players that make up that team so not sure if the Spanish FA would even approach him based on that.
