Interesting that Wenger has changed his philosophy with this competition. Played a much stronger team against Spuds. He knows they need a trophy and his players need to learn how to win.
This is an interesting question, the status of the players AW is starting in the CC. I think there's definitely something to what you're saying, but it's also possible to overstate it.

None of the players who played last night are clearly first-choice in the league. The only 3 who might be considered as such are RVP, Wilshere, and Kos. But Squillaci and Vermaelen are currently injured, so Kos had to play. Wilshere is a starter when Diaby isn't fit (though he may have played himself ahead of him by this point). RVP, for fitness reasons, is behind Chamakh right now; this was very much a play-yourself-into-shape game for him. The rest are clearly second-team players.
I think the most significant difference is not in selection strategy -- still second team -- but in the nature of the second team. A couple of years ago, our second team was young and inexperienced -- at the same level as players like Jay Emmanuel Thomas and Henri Lansbury. Now they're less so; we're deeper in quality than we have been. The genuinely young/inexperienced players are at the fringes of a larger squad; they're more like the third team.
Another important factor is that our squad is healthy right now, at least relative to the horror show of the last couple of seasons. So AW has a deeper squad (better players) that he needs to give games to.
