Unless Pep or Klopp quit, City and Liverpool will remain contenders in EPL and CL beyond this year. Others like United, Tottenham, Chelsea will get raided and won’t be in CL QF next year. Especially if Bayern and Real go all out in the summer.
The third UEFA competition should be made up of clubs that were relegated in each league in the previous season. Then the winner gets into CL group stage in pot 1.
