The Republic of Ireland will be desperate to avenge their nightmare defeat in Yerevan when Armenia come to Dublin for this World Cup qualifier.
After the high of coming from 2-0 down to salvage a draw at home to Hungary, the Irish plumbed the depths when they crashed to a 2-1 defeat in Armenia.
All three bets landed for me in that game but it was a painful night for the Irish as it left them playing catch-up at the bottom of Group F.
Heimir Hallgrimsson parked the bus in Lisbon on Saturday night in a bid to get Ireland's campaign back on track and they managed to frustrate Portugal until stoppage time.
But Ruben Neves headed a late winner and the Republic now need a win over Armenia to keep their faint play-off hopes alive.
Despite losing 2-0 in Hungary on Saturday, the Armenians are also in the thick of the fight for runners-up spot behind the Portuguese.
And if they can do the double over the Irish it would set up a pivotal clash at home to Hungary for that cherished play-off place.
How the bookies view it: Irish eyes will be smiling
Despite their win in Yerevan, the Armenians are 15/2 outsiders with BoyleSports for this one. The Republic of Ireland are 2/5 favourites and the draw pays 10/3.
Head to head: Ireland by a nose
These nations have faced off five times before and there's little in it, with Ireland claiming three wins and Armenia boasting two victories. Both games on Irish soil have ended in home wins, including a 3-2 thriller in the Nations League three years ago.
Players to watch: Ferguson ready to roar
Evan Ferguson had to feed off scraps in Lisbon as the lone striker in a 5-4-1 formation but should get some more ammunition in this game. The Roma striker scored in Armenia and is 5/4 at BoyleSports for another goal.
Eduard Spertsyan netted from the spot when Armenia beat the Irish earlier in the group and the midfielder could offer some value at 5/1 for anytime scorer.
Probable line-ups
Ireland need to win so I'd imagine Hallgrimsson will pair either Troy Parrot or Adam Idah with Ferguson in attack. Midfielder Josh Cullen is suspended after his yellow card in Lisbon.
Monchengladbach forward Grant-Leon Ranos could return for Armenia after coming off the bench in Hungary.
Republic of Ireland: Kelleher, Manning, O'Brien, Collins, O'Shea, Coleman, Smallbone, Molumby, Azaz, Parrot, Ferguson.
Armenia: Avagyan, Muradyan, Piloyan, Harutyunyan, Iwu, Spertsyan, Hovhannisyan, Tiknizyan, Zelarayan, Barseghyan, Ranos.
Anything else catch the eye?
We've only seen four card across Armenia's first three qualifiers so there could be some value in betting against a busy day for the ref. Under 3.5 cards could be worth a punt once that market is priced up while betting against both sides picking up a card may also pay off.
Ireland offered little in attack against Portugal but they need to go for it in this game and should rack up a few corners. Over 6.5 Ireland corners pays 6/4 at BoyleSports while over 4.5 first-half corners is 23/20 with the same firm.
The last meeting in Yerevan was pretty open and seven of Armenia's last eight games have seen over 2.5 goals. BoyleSports price that bet at 5/6 and it looks worth a punt based on those stats. Adding on BTTS boosts the odds to 17/10.
