Like the Welsh, Northern Ireland won't be there either. Unlike the Welsh, we're already mathematically certain of our absence!
Seriously, it's better for our players to be there - if they are at a loose end next summer, thinking of what might have been, that won't do a lot for their spirits. The World Cup Finals next year are relatively early in the summer, so there will be time for rest afterwards.
A successful international side is probably beneficial to us - much of the core of our side is still English, after all. And if our forwards get the nod, in whatever combination, and perform well, that can only do the Liverpool cause good.
Just knock 1966 on the head, will you?!
