Luis Enrique is indeed a major candidate for future coach positions. One has to consider the current assistant coach Jordi Roura a candidate as well (following the way Tito was appointed). Tough to say what's for Pep in the future. Hopefully Tito succeeds like Pep and stays for many years though, liking him a lot as a head coach already. Never would've thought the change of a coach from Pep to someone could feel as ok as it feels with Tito.
