Domestic tournament with a foreign referee

In the following couple of nights the European Champions league will continue quarterfinal plays with its second 90 minutes, while on the other part of the world this tournament under the same name is going to write a little bit of history. As well as in this competition, it will also play games with its second leg, the only difference here is that we are one round higher than the mentioned one.
Slowly and slowly we may say that 'men in blue' are becoming too boring to be referees within its own borders of confederation, but no one thought that this unusual move will come...and yet is still possible. As part of the agreement signed between Asian and CONCACAF regions from 2017, officials from the North American organization came to this unique idea: last Thursday it was announced that an AFC referee will lead a CONCACAF Champions league game. One of the best referee at its zone Ravshan Irmatov from Uzbekistan is going to be a main one at the Scotiabank CONCACAF Champions league (full name of the competition) game between Club America and Toronto FC. This second leg of the semifinal is going to be played on Wednesday, 11 April at 04.00 CET which is equivalent to Tuesday, 10 April at 21.00 local time.
Part one is never enough, so part two have to follow: in October CONCACAF is going to return the favour where will send its well known official to lead an AFC Champions league semi final game.
