Goalkeeper Wayne Hennessey says World Cup qualification would be "absolutely amazing" for Wales.
Wales will reach a first World Cup since 1958 if they win their play-off final against either Scotland or Ukraine on 5 June.
In an extended interview with BBC Sport Wales, Burnley goalkeeper Hennessey also talks competition for places, his friendship with Gareth Bale and receiving his 100th cap from his hero, Neville Southall.
