No correct answers so far. To make it totally clear I meant played at the World Cup Finals while on the books of a Welsh club. Walter Boyd was with Arnett Gardens when he was at the World Cup in 1998. Joined Swansea in 1999. Neither Ante nor Jimmy made it to the World Cup finals.
Think Lawrence may be the right one. Forgot about him. Sorry Dennis. [Edit: Bloody hell - just wikied him and he's on the coaching staff at Everton! "First team development", no less. Well done Dennis!]
