It seems Norway chose to play against Lithuania (see Google Translation to English in case your Norwegian is a bit rusty) in June and not a more dangerous opponent in order to keep their first pot position.
The Danish media and football officials consider this to be a "manipulation".
However, Norway didn't always play against weak/medium opponents and they didn't always win.
Lost to Poland, Croatia, Ukraine (twice), South Africa
Won against Republic of Ireland, France, Montenegro, Slovakia, Switzerland, South Africa, Finland, Germany.
In a July ranking counting only friendlies (see the second table), Norway were 3rd in Europe, behind Spain and Netherlands.
And if anyone asks - I had nothing to do with this, although I think the Norwegians did what they had to do - it is not illegal.
