What's at stake?
Whoever wins the play-off final will earn themselves a place at the World Cup in Qatar in November. The winner will join England, Iran and the USA in Group B.
How did Wales and Ukraine reach the play-off final?
Wales qualified for the play-offs courtesy of a second-placed finish behind Belgium in Group E. Their only defeat in the entire campaign came against Roberto Martinez's side in Leuven, having beaten the likes of Belarus, Estonia and the Czech Republic.
Despite being slight underdogs, they booked their place in the final by beating Austria 2-1 in Cardiff. Captain Gareth Bale struck twice in what was a frenetic encounter at the Cardiff City Stadium.
Meanwhile, Ukraine didn't lose a single game during their qualifying group stage, drawing six and beaten Finland and Bosnia and Herzegovina. Two of those draws came against current World Cup holders France, with Les Bleus being held 1-1 home and away.
Have Wales or Ukraine ever played in the World Cup?
Wales have entered every World Cup qualifying campaign since 1950, but have only made it through to a finals on one occasion. This came in 1958, when a team containing the likes of Cliff Jones and John Charles battled through to the quarter-finals with three group stage draws and a play-off victory against Hungary. They were eventually knocked out by Brazil in the quarters, with a 17-year-old Pele scoring the only goal of the game.
Ukraine, meanwhile, have only qualified for the World Cup once since breaking away from the Soviet Union. They defied expectations in their one and only appearance in 2006, however, as they reached the quarter-finals only to be beaten 3-0 by eventual champions Italy.
