Wales manager Chris Coleman is remaining hopeful on Gareth Baleâ€™s availability for tomorrow night.
The Wales boss has his fingers crossed for Bale but insists the player will not be risked if he is too ill to set foot on the pitch.
"He came up after us, took a later flight, he was suffering for a few days with an illness, which he contracted probably Tuesday or Wednesday. But he's okay, got a later flight and he's at the hotel," Coleman told Sky Sports News.
"Well I wouldn't like to give too much away but he's got as good a chance as anybody else of starting.
"We won't risk him, he's Tottenham Hotspur's player. He turns up most games for us and he's been brilliant for us, but if there's any risk we won't play him.
"We've got today and tomorrow. He's with us, he hasn't trained this week, but he has had a lot of games. Sometimes it's good for players to have a little rest.
"We'll be guided by Gareth predominantly, but we're optimistic. He's here, he's with us and hopefully he'll be ready for tomorrow night."
