Chris Coleman expects a physical battle when Wales' World Cup ambitions go on the line at home to the Republic of Ireland.
The Dublin game between the two countries in March descended into controversy and ill-feeling when Republic captain Seamus Coleman had his leg broken in a challenge with Neil Taylor.
The Wales defender was red carded for his tackle, but Wales held on in the final 20 minutes for a goalless draw and a precious point.
Emotions are certain to be running high in Cardiff on Monday with Wales, second in Group D, and the third-placed Republic meeting to determine who reaches the November playoffs.
Wales and the Republic can both still win the group -- and secure automatic qualification for next summer's finals in Russia -- but for that to happen Serbia must falter at home to Georgia.
"We know what the Republic are good at," said Wales boss Coleman, who faced a hostile Irish press corps after his namesake was badly injured at the Aviva Stadium.
"But this is the last game of the campaign, all or nothing for both teams.
"So even without the unfortunate incident in Dublin with Tayls and Seamus, this was always going to be a game where there will be two teams locking horns.
"There will be lots of contact in the game, it will be physical, good players, and not much in it.
"But even before what happened [in Dublin] it was a physical game and we expected it to be. We were all absolutely devastated at what happened.
"Seamus Coleman is such a good player and you never want to see that happen, but there won't be any mention of the unfortunate incident.
"We're just going to go with our game-plan and make sure we're 100 percent focused on doing what we're good at."
Those principles have served Wales well in recent times under Coleman.
Friday's 1-0 win in Georgia extended the record of the Euro 2016 semifinalists to only one defeat in 21 qualifiers.
And, after successive victories against Austria, Moldova and Georgia, Wales could now make it four wins in a row for the first time in 36 years.
"It's all about performance and the game-plan and executing that," Coleman said.
"The last three games we've had, we had to wait until the last 15 minutes -- against Moldova away, we beat Austria with something special, and we've gone to Georgia, a tough place, and ground it out to get a result.
"That's what it's about. It's not always going to be that you win two or three nil, you play fantastic football -- Baleo (Gareth Bale) puts in the top corner and Rambo [Aaron Ramsey] runs the game."
Bale will again be missing on Monday with the calf injury which ruled him out of the Georgia trip.
The Real Madrid forward will be watching on at the Cardiff City Stadium, but Tom Lawrence proved in Tbilisi that Wales now possess extra attacking options.
"I can't wait for the Ireland game now, the atmosphere is going to be unbelievable," Lawrence said after his stunning 25-yard winner in Georgia.
"Everyone in the squad is there to do a job, I've done mine in previous games and then Ben (Woodburn) has come on and done his. We're all in this together."
