|9/2||Arsenal are 9/2 with Betway to win the FA Cup|
The Gunners slumped to a 5-1 defeat at Anfield on February 8 but the Frenchman believes the chance to play Brendan Rodgers' men so soon after the fixture provides added motivation.
When asked if he would rather have avoided Liverpool in the FA Cup, Wenger replied: "No. I would say that it is the first team we want to play. When you can put things right, you want an opportunity to do that and we have an opportunity.
"What will decide our end of the season is to focus completely on every single game. I believe on that front, the fact that we do not play against a Championship team but against a Premier League team will help."
Wenger also says the Arsenal crowd will be fully behind his team on Sunday, although he has urged his team to get fans onside with a strong performance.
"I sense a huge feeling from the crowd to help the team but we have to strengthen that belief with our performance," Wenger added.
"The crowd will no doubt be behind us [against Liverpool] but let's put the vibes out that we have a go and they will be behind us. They were hugely behind us on Wednesday night [in the 0-0 draw with Manchester United], they were frustrated at the end of the game like we were.
"If they were not behind the team that would be a surprise. We are one point off the lead, we play in the Champions League and we play in the FA Cup. If, on top of that, we have not got a crowd behind us that would be absolutely unbelievable.
"After that if you can help [get the fans] behind the team that makes us even stronger. But we cannot expect too much. Let's have the attitude to have the crowd behind us. They were behind us at Liverpool, when we were 4-0 down."
