The Gunners host City at the Emirates Stadium and it is likely that Frimpong will start in midfield alongside fellow young gun Francis Coquelin. He says that no matter who Roberto Mancini deploys for the visitors, he and Coquelin can do a good job for Arsenal.
"It's going to be a tough game, no doubt about it," he said in the official matchday programme.
"If we win, we'll have two more Carling Cup games and be on course to go all the way. It's very important to try to win the competition this year, and go one better than last season - and on a personal level it's important to get games under my belt.
"I think it's going to be a very exciting tie, and hopefully we'll get the right result. Whoever City put out, they'll have good players in the midfield.
"But regardless of the players we're up against, I think Francis and I can perform against anyone if we're at our best on the day."
