What do people expect for an interim? Pep Guardiola? Valverde until the end of the season + Hag and Overmars taking over is the perfect combo, really. Yeah, you can argue Valverde won't deliver scintillating football, but he knows how to grind wins and as far as I'm concerned, at this point that's all we need. We can worry about pretty football when we salvage this season. Obviously I do not believe the men in charge are that smart to do something like this, but this is quite literally the best option we have right now. The other one is Poch coming here right now, but that's very unlikely at the moment.
But probably the end result would be Valverde now and Poch at the end of the season instead of Hag which would be underwhelming, to say the least.
