I can see that happening unfortunately.
The annoying way Selles keeps reminding us he wants to be here for the next 10 years, has Ankersen's "failed managers get better" philosophy all over it. Plus of course Selles will be very cheap probably the cheapest in the Championship which is typical SR. We have lost 23 PL games and counting having won just 6. Sunderland just about made it to the play off on GD, losing 13 and winning 18. Saints need a Tony Mowbray, Daniel Farke or a Chris Hughton, managers that have won promotion. People like Selles should be nowhere near SFC.
Hmmm....I understand your fear, and I do worry that Selles will be able to sell the whole "given a full pre-season, I will be able to implement my philosophy, which I couldn't at the point of taking over" line.
But in some ways, I'd almost rather that than a Hughton style appointment, which is all a little bit jobs for the average boys/Big Sam. If we are going to change manager (and I hope we do), there's no reason why we shouldn't go down a Carrick/Vieira route of a young, up and coming, bright guy (though I'm also sure that Selles considers himself such as well, it just remains to be seen if SR/Wilcox do), rather than tried-and-tested 'useful in the Championship, but you'll get rid of them the minute you get promoted' types.
Ankersen for all his myriad faults doesn't strike me as a short-term fix type.
