Two of the four home nations go face-to-face in Paris on Saturday, as Wales take on Northern Ireland in a Euro 2016 last 16 clash.
Having beaten England to top spot in Group B by taking six points from nine, Chris Coleman's men are even money (2.00) favourites with bet365 to get one over on another neighbour by securing a victory at Parc des Princes.
Meanwhile, a single group stage victory was enough for the Green and White Army to progress as one of the four best third-placed sides, and they are on offer at 4/1 (5.00) to double their win tally by coming out on top here.
The sides shared a 1-1 draw in a pre-tournament friendly back in March, and there are odds of 21/10 (3.10) available on them taking this one into extra-time with another deadlocked 90 minutes.
Although they finished on the same number of points as Turkey and Albania, Michael O'Neill's men advanced to the knockout stages ahead of them thanks to a superior goal difference.
Having restricted the talented attacks of both Poland and Germany to just a goal apiece in slender 1-0 defeats, a 2-0 victory over Ukraine was enough to balance the books and secure a place in the last 16.
These results will have surprised nobody that has followed O'Neill's tenure, with his team having now conceded just 18 goals in their last 25 fixtures.
In fact, the sturdy Northern Irish backline has not been beaten more than once in a game since a 2-0 defeat to Romania back in November 2014, so should feel confident of restricting Gareth Bale and Co. to a minimum of chances in the French capital.
Considering the Dragons have only conceded eight goals in their last 15 competitive matches themselves, odds of 6/5 (2.20) look like strong value on under 1.5 being scored in a tense knockout tie between two local rivals.
