The whole contract situation suggested to me Edwards thought he deserved higher placement within the squad, and was likely courted by a bunch of teams offering him first team football. So I *think* Edwards likely feels he deserves to be in the first team squad.
If Pochettino is "playing mind games" at all it is likely to have Edwards realise where he actually stands, and what is really required to break through.
There is no room for complacency in a Poch team, and nobody gets in without 100% having earned it.
It looks like Pochettino is having that hit home. Given Edwards talent I fully expect to see him this season. How soon, and how often, is most certainly down to him though. If he gets on board with Pochettinos expectations then he will succeed.
And to be fair to him, it does sound like he is knuckling down, which can only be good.
