Well let’s be honest and admit that we’re both going to be a tad biased in that regard. ;-)
If we’re going to try to be objective, however the first sentence could apply equally to Foden, and who knows how long Guardiola will be with us. We can either view Sancho as impatient or we can see him as someone who was confident in his own abilities and willing to back himself. He now has experience of working under Bosz, Stoker, and Favre, so a wider range of perspectives, and he’s a talented boy so will learn from good players because he’s going to be playing at top teams.
As you say, time will tell.
