I think Pep just made a mistake. I know it's almost sacrilegious to say, but if he'd had his way then we'd have ended up with Alexis Sanchez and I think he just got too fixated on a player we didn't need, which drove Sancho out.
Sancho was impatient, definitely made some mistakes in the way he went about it, but given our record with youth players and the success he's had at Dortmund, it's very hard to criticise the decision.
Ultimately, bringing him back is about who the best signing is, and outside of Mbappé, he's the best forward in his age group, and the fact he'd be club trained home grown is genuinely worth tens of millions to us, because it opens up a squad place.
