Slovakia, Wales and Russia would have probably qualified also for a 16 teams Euro looking at qualifying groups results. Also Northern Ireland, Czech Republic and Austria.
So maybe your complains are a bit misplaced?
England really got a lucky group draw and gets to complain about not banking on that now.
Agree all of them would of qualified and to be fair Wales have looked pretty good but its not the teams that have qualified its the best 3rd placed qualification thats the issue its promotes parking the bus for these sides
