"I'm sure the international boys want to play," Young told BBC Sport Wales. "They've obviously got to get used to the calls again, and the fatigue and mental stress factors are massive.
"But all the Wales boys are big players for the Blues and we're looking to get them back as soon as possible. It's a massive month for us with some mouth-watering matches over the next four or five week period. They are huge games and promise to be very exciting.
"These are games that we have to be at our best to win but I'm sure we can match with the best of them. The crowds have made a difference.
"It's massive for the team to have a full Arms Park and hopefully very vocal support getting behind us. We've got a part to play but I'm sure we can do that, and I'm looking forward to having great support the way we always do," he added.
