In Moura's MOTD post match interview he said words to the effect that we (they) all need to be together and not speak too much. It struck me as a very deliberate thing to say.
There have been comments from Dier and Winks, (presumably from the post-match mixed zone?) - much to the same effect - togetherness. So I do wonder if the players have decided amongst themselves to keep any comments to a minimum, with Sissoko's being the agreed social media post, rather than feed the frenzy. Perhaps they recognise the situation has moved beyond platitudes and soundbites.
If it's a sign of the squad regrouping, that would be a good thing. Well, as long as they're not shutting out Poch in doing so.
Alternatively I'm wallowing in far too much saccharine-coated sentimentality about the whole thing and the silence means the vibes are bad and they're at each other's throats!
