We would certainly be having a huge fall from grace if we aren't in the top 25 when the draw is done. Less group games in stage 2 than last round with only 6 match days required rather than 10. May create a bit of space for a nations league.in the back end of 2023.
Had another look at the FIFA windows and if they keep the 5 windows a year going the first round must start in the Sept 23 window with the first group stage starting in October. Using every window the second group stage finishes June 25, with stage 4 happening in the sept window, the playoff in Oct and the intercontinental playoff in November 25. There is no space for a nations league.
