Wales play their first World Cup match for 64 years when they take on USA in Al Rayyan this evening.
The last time the Welsh were on this stage they were knocked out by a prodigious talent named Pele, but they have been making waves at major tournaments more recently and will be looking to get their campaign off to a winning start.
USA were also absent from the last World Cup and so they too will want to make up for lost time in a group which has already seen England put down a marker with a big win over Iran.
Here, Sports Mole compares both squads to see how they stack up against each other ahead of the contest.
