I would only sack Koeman for Gallardo tbh. Ten Hag won't leave Ajax before next summer (so why pay out Koeman only to replace him with probably an inferior interim manager if Ten Hag is your target?) and I just have a feeling both Xavi and Laporta think it's not the time for his return yet so nothing will happen on that front for 2-3 more years at least.
Yeah, that's my point. If we can get one of those three now, great. If not I would rather keep Koeman for now. And try in January for Gallardo, who should be the easiest to get (unless Xavi really wants it).
