Squad been announced and only Lewis Charnock from Saints makes the squad. 8 players from Wigan as the England team is coached by Wigan coach John Winder. The players picked are not the best in the country. Theyre the players picked from a biased panel.

SICK TO DEATH OF YOU TROLL NUMPTIE, JUST DO ONE!

Wigan have been the best 19's team in the league this season and these 8 have earned their call ups in my opinion.
They were all in the squad for the game in La Reole where they won their game by a big scoreline.
Thompson and Sutcliffe were both in that squad and would have been in this if available I assume.
Is Percival still under 18's this season?

I agree with this. Wigan coach or not, it's pretty obvious Wigan have good youngsters.

Saddened, we have produced good quality youth this season. The likes of swift, Thompson, Percival, Walker, Greenwood (sure I'm forgetting someone) have all came through or developed as better players this year.

Wellens?

Rumour has it Warrington turned down Wellens as a replacement for Hodgson as he's "Too young"
