Wales captain Ashley Williams says the crunch World Cup clash with Serbia evokes memories of their momentous victory over Belgium in Euro 2016 qualifying.
The 1-0 victory over Belgium - who were ranked second in the world at the time - in Cardiff 17 months ago was a huge step towards Wales qualifying for France last summer, where Chris Coleman's side would eventually make the semi-finals.
That win came at a pivotal stage of the campaign and Williams feels there are echoes of that contest in Serbia's trip to Cardiff, with the Group D leaders currently two points clear of third-placed Wales.
"It has a bit of a similar feel to that Belgium game," Williams said.
"We need to give the fans something to get excited about and we want them to have that same atmosphere to drive us on.
"Hopefully then we can have another evening similar to that one."
Gareth Bale's early goal against Belgium in June 2015 g ave Wales something to hold onto in the face of mounting second-half pressure from the Red Devils.
Sensing that the players were tiring, the Cardiff City Stadium crowd responded with an impromptu version of the Welsh national anthem and Wales found a second wind to keep Belgium at bay.
"Normally you're so involved in the game you don't really take notice of what's going on," Williams said.
"But when they started to sing the anthem it was so loud that you had no choice but to stop for a minute and realise that this was something special.
"Towards the last 20 minutes when we were tired and cramping up, they drove us on to get the win.
"I remember at the final whistle 'Gunts' (Chris Gunter) rugby tackled me onto the floor and he was emotional.
"I thought 'I've never really seen this before on the pitch' - and that's when I knew this night was something that I would always remember."
Serbia's visit is Wales' final game of a calendar year which will never be forgotten in Welsh football.
But Williams accepts Wales have work to do following last month's draws against Austria and Georgia.
It has left them playing catch-up on the road to Russia 2018, and there is little margin for error with their n ext two games away to the Republic of Ireland and Serbia.
"This is massive, we know this is an important game in what we are trying to do," Williams said.
"In recent years we've always faced up to the challenge and responded when it is a big game.
"It's been a good year for Welsh football and we want to finish it properly.
"But, more importantly, we have a job to do in this campaign."
