Old Trafford’s muddled succession planning has seen a host of talents flop but the Sporting manager shares that outsider glow

Forget the details, forget the noise. Forget the specifics. Imagine you run a big club on a losing streak. You are looking to appoint a new manager. What do you want, ideally? You want a young manager on the way up, someone fresh, with vision and drive and personality. Someone who could perhaps still be leading the club a decade later.

At the very highest level, most managerial careers are relatively short. The notion of a “proven winner” is a consoling but meaningless shorthand. There is no such thing; everything is fluid, everything is contingent; there is always a context; every career has an arc.
