Wales and Northern Ireland will provide an entertaining affair of contrasting tactics in an all-British last-16 fixture at Euro 2016.
The Dragons topped Group B in style with a 2-1 win over Slovakia and a dominant 3-0 win over Russia – their 2-1 loss against England was the only negative to their already impressive campaign thus far.
Norn Iron managed to secure a place in the first knockout round after a memorable 2-0 win over Ukraine, which marked their first-ever victory in a major tournament.
Michael O'Neill's side have only lost two of their past matches but both have been at the European Championship.
Their inspiring defensive performances during 1-0 losses to Poland and Germany respectively were crucial to their qualification from Group C as one of the best third-placed teams.
Gareth Bale, who is currently joint-top scorer of the tournament with Spain's Alvaro Morata, believes the Welsh may go on to win the tournament as they'll avoid the likes of Germany, France, England, Spain and Italy en route to the final if they win all their remaining games.
"Obviously you come to the tournament for one reason – to win, not to play three games and go home," Bale told reporters.
"The ultimate goal is we want to try and win the tournament. It's a cliche but we'll take each one as it comes. Yes, we would love to win it, but all our focus now is on Northern Ireland."
Northern Ireland have won none of their past eight games against Wales as they prepare for a first meeting between two British teams in the knockout stages of a major tournament.
