For me this is the problem with today's football. World Cup, Euros, Nations Cup along with every other possible extension of all the domestic and European competitions. What is the Nations Cup? I know it exists but for the life of me I can't see a purpose to this competition.
When will the game's administrators learn less really is more?
Paul, the Nations League was implemented to put competitive games in the slots where friendlies used to be.
A lot of people are playing down it's importance but results in this league affect rankings / seedings for future Euros / World Cup qualification groups.
Unfortunately for my national side (Wales) we do not have the strength in depth to play the 5 games in 14 days we have had to play this past fortnight (witness the team we put out in Poland!) and it will come back to bite us in the future with regard to seedings.
Another by product of this league is that some of the best performing get play off spots for major tournaments.
I get the tournament and the games are usually more spread out but I think this fixture pile up is a result of a winter world cup and for us, Scotland and Ukraine the postponement of our World Cup playoff which should have been in March.
