No problem with that lineup at all.
This game was an opportunity to do one of two things. One, put out a bunch of squad and youth players and see if anybody excels enough to warrant a place in the regular side. Or two, put out a full strength side having had time to work in training on the system and expectations against weaker opposition as a warm up ahead of a very important game against Palace.
Potential downsides today are obviously not getting a result means morale stays low, at least among the fan base, and of course the risk of injuries given we're putting out key players. But injuries can happen walking the dog. Upsides are obvious.
