All opinions do not have equal merit because they don't have equal backing to them.
I can speculate that Txiki Begiristain is actually an alien called Zog and his recruitment policy is a way of bringing his alien shapeshifting friends into Manchester to begin a world invasion.
This doesn't mean that's unchallengable or equal to the opinion that Txiki is working with the coaching staff and the scouting department to identify targets then going to the board with estimated figures to begin negotiations for them.
One of those is based on something and the other isn't.
I think that any recruitment strategy that has Gabriel Jesus, Sterling, Sane, De Bruyne, Stones, Fernandinho, Otamendi and others in it cannot be called "poor", no. Again, his job doesn't rely on the performance of the players - it relies on whether they have been useful to the sqaud.
Maybe. Or maybe you can build a point that isn't based on speculation of speculation of speculation and see where it ends up instead?
