Yep agreed Europe has incredibly talented officials coming through and more to come with the likes of Maxwell-Keys, Ridley, Grove- White, Busby, Blain, Ruiz, Amashukel, Piardi, Whitehouse & Evans. I would expect Barnes, Poite & probably Gauzere to retire after the next World Cup with plenty ready to take up the mantle.
I would expect to See Barnes in the semis/finals though!!
