Not that the idiots running the club would but if we should be doing succession planning for our very best players then I think the replacements ought to be here already, either signed in the summer or January before
Where we are these days means even if we could we aren't getting players at the same level so it buys the club time to review how the player is performing, it gives the player the opportunity to get used to Premier League football, acclimatise to the UK and Wolves way of doing things.
I mean, if you were properly mental you could play the succession player in a midtable clash with little riding on it and rest your best player for a cup quarter final the following weekend, and they'd get plenty of minutes as you manage the minutes of your better players.
As it is, you're only ever a player failing to settle, or failing to deliver from going on a January supermarket dash.
Of course there are exceptions here, but if we've made our bed that we're a selling club we should be anticipating when each player (of value) will likely move on and plan for that well before they do.
