I respectfully
entirely disagree but that's a theoretical debate which we can't solve.
The thing is that English teams underestimate how much they drop UEFA coefficient points which doesn't just have an impact on the English coefficient but on the club.
With the new access and seeding rules, even Real Madrid who lead in the UEFA team ranking is in pot 2 unless they win the CL. Similarly Atletico who are 4th but will be in pot 2 unless they win the CL.
If United were to play CL next season, they'd be in pot 3. If you don't do well in the EL, Shaktar who are already in your neck could overtake you as you loose about 16 points in the 5-year calculation, they only loose about 10.
