The hosts will be looking to keep momentum going following their morale-boosting 3-1 away victory over Azerbaijan on Thursday. Gerson Rodrigues scored a second-half brace and provided an assist to inspire victory for the Red Lions.
The Republic of Ireland showed great determination and grit to secure a point in a goalless draw with Portugal on home turf.
The two sides have already been eliminated from the race for Qatar 2022. That makes Sunday's game a dead-rubber, although there is the not-so-small matter of deciding who finishes as the 'best of the rest' in Group A.
Luxembourg currently occupy that position in third spot on nine points while the Republic of Ireland are three points behind them with a much better goal difference.

Luxembourg vs Republic of Ireland Prediction
The home side need just a draw to secure third place in the group. Having ended a four-game winless run with their victory on Thursday, confidence will be running high.
The Republic of Ireland need a victory to usurp their hosts and are currently on a five-game unbeaten run. Although one side could nick a win here, we are backing the spoils to be shared in a compact and low-scoring game.
Prediction: Luxembourg 1-1 Republic of Ireland
