Wales Coach Chris Coleman has insisted that he will not risk Gareth Bale if the Real Madrid man is not fit.
The attacker reported for national team duty late on Monday evening after being unveiled as a Blancos player.
But the tactician has claimed that the 24-year-old will not be forced to play in the World Cup qualifiers against Macedonia and Serbia.
"If he is not ready we will not risk him," Coleman told a Press conference. "He has not done much work in the last six weeks or two months. His last training session was with us before the Republic of Ireland game.
"Is he going to start on Friday? I think that may be a doubt [but] that's not to say he can't play a part though," Coleman added.
"We'll see how the next two or three days go in terms of where he is physically and mentally because it's been very draining on him. The main thing is, he's here.
"We are aware a lot of people will want to see him play in the home game against Serbia. But he has no chance of playing 90 minutes on Friday or on Tuesday.
"Credit to [Real Madrid], they have not put any barriers in front of him and there hasn't even been a conversation. They've allowed him to come back," he added.
"I know Carlo Ancelotti's right-hand man Paul Clement very well, he coached with me at Fulham, so that can help us going forward when I go out there to speak to them."
