Unfortunately I think I started this by pointing out Davies development would be affected by the managerial situation. I do think that has been lost somewhat by the following debate. As with most young players, their opportunities will be affected by how willing a manager is to get the best out of them. Part of that is playing them, but also part of that is knowing when not to play them. Whether we think Martinez is good or bad with youth is secondary to that point.
I have been a big advocate for playing younger players and I think we could have blooded more. At the same time for the Derby I would go in with as much experience as possible. It threatens to be a truly hellish night with them on a role and us badly out of form. We will need big characters, cool heads and experience. Football isn't a computer game, if we get hammered it could do a lot of damage to the squad and the young players. I think we have to treat it as we did under Smith/Kendall. Ie we ar ethe inferior team and we need to have 90% of our focus on stopping Liverpool.
As for Davies I would have him on the bench. I'd start Gibson and if Gibson ran out of steam and the game was close I'd bring Davies on. Connolly I wouldn't start as he will be exposed by Coutinho.
