Pretty simple, Everybody who didn't feature against arsenal starts, the ones from the bench will likely have to too then fill it out with kids. Should be more than good enough to win and if not, it avoids numerous schedule headaches further down the line.

That side should be able to carry a couple of kids against watford who could very well put out a second string of their own as even championship sides tend to do that now and then put a few more kids on the bench for if we make it comfortable and can rest some of the first team. Don't even want to see the likes of haaland on the bench.
