Why is it one or the other?

If Kieffer Moore comes off when looking tired against Stoke we're more likely to pick up 2 extra points, if he comes off when looking tired the result is unlikely to change because his contribution was minimal by that point and so he's got more gas in the tank to play the internationals. By working with better players he improves his game, and by scoring increases his confidence, so returns to play better for City which improves his form here and can take it into the games over the summer....

Joe Allen playing 13 games in few weeks in so many weeks for Stoke now is injured for them and likely to be short on match-fitness for us...

Success for one is almost definitely going to feed into success for the other, but ultimate success is unlikely for either.
