Wales manager Chris Coleman believes the 'holy grail' of qualifying for a major tournament is within reach if he can play his best team in the Euro 2016 qualifiers.
The campaign starts in Andorra on 9th September, but it is the games against group favourites Belgium and Bosnia-Herzegovina as well as Israel and Cyprus which will determine whether Wales make it to France in 2016
Wales haven't qualified for a major final since the World Cup of 1958.
But, there is real hope this time that Coleman can turn that around by guiding a talented group of players to an expanded 24-team championship.
We're going into it with enthusiasm. Expectations are always high and it's all to play for. The holy grail for us is to qualify and we've got a chance to do that over 10 games with a little bit of luck. That's the objective.
Real Madrid superstar Gareth Bale heads the list but Coleman can also call on the likes of Arsenal midfielder Aaron Ramsey, Liverpool's Joe Allen and Swansea skipper Ashley Williams.
The squad will be announced later today.
