Wales coach Chris Coleman believes Gareth Bale needs protecting as he does not want the Tottenham Hotspur winger to suffer from burn-out.
Bale has established himself as one of football's most dangerous attackers over the past couple of seasons, but is often troubled by a hamstring problem.
He missed the Gary Speed memorial match against Costa Rica in midweek and there were reports that the 22-year-old could be sidelined for several weeks.
Spurs boss Harry Redknapp shrugged off those suggestions, but Coleman believes that a prudent approach needs to be taken with Bale's fitness.
"Gareth has had a problem with his hamstring for a long time," said Coleman in The People.
"He is hardly training at Tottenham but he's playing the games. He has had a lot of football this season, a lot of football last season. He is going to get niggles.
"When Gareth says his hamstring is tight, you know why. He is only 22. We forget that. It has been a whirlwind for him the last couple of years and he's now one of the best left-sided attackers on the planet.
"He needs to be protected. I am afraid he will get burnt out. He will be afraid of it. He has been here with us all week and the medical team have kept an eye on him because he's not someone you want to risk.
"It's different for Gareth Bale because he is Gareth Bale and every time he walks on to the pitch people expect. That's an added pressure.
"It is a sensitive situation and we have to be understanding of it and we will be. He knows how important he is for us.
"We have to understand it is a long season with the Premier League, the FA Cup, the Carling Cup, the Europa League and Wales."
