We do move players from U23s to first team bench, Pears and Spence were moved into first team last year, Coulson was U23s the year before, and Wing and Tav the year before that.
The path to first team tends to be through injuries and suspensions. With a small squad, I think some of these lads will get a chance. We've already seen, Woods and Folarin get on the pitch and Brynn on the bench. I would expect one or two others will get the chance. If we get a CM injury then Wing will be in the side and we will need a CM on the bench, Hackney. Yes Burrell might be a striking option, Kokolo at LB although we have at least 3 options in that position.
