Tyler Adams revealed he has already spoken with USA's defenders about the threat of Kieffer Moore having played against the Wales striker for Leeds United against Bournemouth.
Adams - who has been announced as his country's captain for the World Cup - will lead his players out in their Group B contest against Rob Page's troops on Monday night, but he admits the USA need to keep a close eye on Moore.
Indeed, the towering frontman has nine goals in 28 international caps and has netted five times for club and country so far this term. And Adams believes Moore is underrated given his ability to hurt opponents in many different ways.
