I agree with this. Even players not picked for their international sides should be good enough to step up for a couple of games. I hate the way the season is broken up with these breaks. Not going to happen though.
I'm sure I remember back in the 50s international (home internationals) being played on Saturday afternoons, at the same time as the league fixtures. So if your star centre half, left haft half, inside right or whatever was called up, you just played his understudy instead. Can't see that happening again, either.
