Daniele Orsato (ITA), Danny Makkelie (NED), Szymon Marciniak (POL), Anthony Taylor (ENG), Clément Turpin (FRA).
One of these for the final?
I would rule out Marcinak.
Does the fact that working with VAR week in, week out rule out Hategan?
Romania, like Hungary, use the Saudi League for VAR experience for their elite refs. Hategan did around 6 games there last season (as in 19/20) as referee and normally while there they do a 2nd game as VAR as well to also get that experience. He also had at least 1 appointment in the King's Cup there as well as the 6 in the domestic league which is another VAR game under his belt.
They actually often do 3 games whilst there - one as ref, one as 4O and one as VAR so they get the VAR experience from all 3 positions. At least our refs from Hungary do and I would assume it's the same for Hategan and Kovács from Romania. The Saudi League are very accomodating in that regard mainly because they get a lot of foreign elite refs doing their domestic games which helps them preventing similar allegations the Russian league is blighted with!
