I actually don't understand what Pep's plan is when he plays with Zinchenko.
Zinchenko tucks in, so Sterling is wide on the touch line --> Ineffective because he is right footed and so far from goal, he isn't crossing on his weaker left foot
Zinchenko goes wide, so Sterling plays inside --> Better position for Sterling, but then Zinchenko is useless as he doesn't cross and we have no left side attack, plus he is too slow to track back counter attacks from such a wide position
Pairing the two doesn't make sense to me.
If we buy Bailey, then I can see Zinchenko and Bailey playing together, but I've never liked this pairing.
