Cape Town - Arsenal manager Arsene Wenger wants his players to avenge their trip to Anfield earlier in the season when they face Liverpool again on Friday.
The Gunners were beaten 4-0 back in August; a painful result that the French coach wants to make good at the Emirates Stadium.
"When you have such a long career as I have, you have some defeats, unfortunately, that hurt you for the rest of your life," he said.
"I believe what is interesting in football is you always have a time to make up for it. When you can put things right, do it.
"So let's focus on what is in front of us and turn up on Friday night with a completely different performance.
"The motivation is there. This squad has a good mentality and it is about us, to make sure we are on top of our game. We must play with pace and a determined attitude."
Arsenal are just one point behind Liverpool in the Premier League standings heading into the match, but face an opponent unbeaten in their last nine league games.
Kick-off is at 21:45.
