The tip-off, of course, came from Sergei Rebrov, whose likely start will swell the Tottenham contingent to two as a long season draws to a close.
"Sergei has already told me there will be 88,000 in the Ukraine, so that one should be good," said Simon.
"He’s told me he’ll be fit for that one so if I manage to get on the pitch it would be great to play against him. I played against him in Cardiff when I made my debut as well. That was a great experience as well, one I’ll never forget."
Simon is a probable starter as Wales boss Mark Hughes looks to the future after World Cup qualification hopes effectively ended with defeat to Poland on Saturday.
Simon is ready, in form and waiting to grasp the opportunity.
"I have had a great end to the season and to do so well in beating Manchester United recently just about capped it all. I'd started the season very much in the reserves, but since the new manager has arrived I have been in the side virtually all the time, which is very pleasing.
"About the only game I have missed was when I was injured in the FA Cup semi-finals - apart from that I've had a good run and it has really helped me with my game and my confidence."
That special ingredient of confidence has all come from an extended run in the first — during which the midfield stylist has won many admirers.
"The extra confidence has all come from the last 10 or so games I have played. It gave me the confidence to run at United like I did, maybe I wouldn't have done that a few months back.
"I've got more confident every game and it just worked out well for me in the United match. It was a big jump up into the Premiership from reserve football, you don't know what to expect.
"Obviously you believe in yourself, but you still have to go out on the pitch against the best in the country and prove it to everybody else."
Looking ahead to next season, Simon added: "It's going to be very exciting next season, but we will have a lot of players back from injury.
"So I will maybe have to wait and see what happens and take my chance when it comes along.
"My first priority will be to get into that first 16 because there are a lot of world-class players waiting to come back."
Simon Davies has been forewarned that he is likely to play in front of the biggest crowd of his career so far if he takes his place in the Wales side to face the Ukraine.
