Cakir must be a lock for a semi now, and I wouldn’t be surprised if Orsato has the other, but if all the English sides perish then Taylor has a chance IMO.
The final... has to be Kuipers.
Given that there are only limited options since the real Elite is 10-12 referees Cakir should be a lock for a SF. Now if Bayern is out then Brych should have a match.
Turpin could also be an option with a good performance in Seville. Orsato could be the 4th name or Taylor if Dortmund eliminates Man. City.
For the final I would say Makkelie or Lahoz (if Real is out).
