It seems you're just a bit older than me, and although I don't know the average age of retirement in Belgium, I'm guessing your boys will make a big tournament before you retire.
Okay then I definitely think they'll qualify before you retire, unless you're rich and plan on retiring in the next couple of years .
I'll be content with them qualifying. It's absurd to speak of a semi-final when you haven't qualified for an actual tournament in nearly nine years.
Realistically if Defour, Lukaku, and Hazard become what we all expect of them, 2018 would be your more realistic top 4 year
