QuincyAbeyie If Saka misses a one-on-one I'm going to call it a bad finish even if I personally wouldn't have done a better job with that chance.
That's a false equivalence. You're not being asked to finish better than Saka, you're being asked to provide some evidence that Saka should have scored.
It would be more like me saying we should have won the treble and then not having to justify that claim by saying 'I'm not the manager on 15m a year' that's Arteta's job.
There's very little evidence to suggest that it's straightforward for a talented scout or manager to identify a centre forward that can raise the level at a top team.
