Uefa unveils plans for Nations League competition in 2018

[WalkerboyUK]

Will qualifying for the UEFA EURO change?

The changes to UEFA EURO qualifying make it more streamlined. The equation is now simple: 10 groups with the top two teams in each group qualifying automatically with other 4 places being awarded to UEFA Nations League play-off winners.

The UEFA EURO 2020 qualifying draw will be held after the completion of the UEFA Nations League and allow for the four UEFA Nations League Final Four participants to be drawn into groups of five teams

But the key principle of the qualifiers remains, that every team can play every team.

So instead of 2 years of qualifiers, we're going to cram it all into one year???
And what's the point of the 4 Nations League Final Four participants being involved in the qualifiers?
What if one of those 4 finishes (as you'd expect) in a top two position. Does 3rd place then qualify??
