The Ivorian is expected to come into central defence alongside Mamadou Sakho as he looks to add to his illustrious career history, with Barclays Premier League and FA Cup winner's medals from his time at Arsenal and City.
Having yet to taste victory in the League Cup, Sunday's occasion at Wembley presents Touré with the perfect opportunity for him to do so - as the veteran defender goes in search of his first trophy on Merseyside since signing in 2013.
Defender's sights set on Wembley glory
"It's going to be big, massive," said the 34-year-old when speaking to Liverpoolfc.com about the stature of the game, insisting that the team "for sure" want to "win this cup" and saying he especially wants to get the better of Manuel Pellegrini's side, which includes his brother Yaya, because he's "never won it."
"As a team we want to win," he explained, adding that he wants to "especially" because he has "won every trophy in the country apart from the League Cup" which he says is "a good challenge" for him personally.
Touré added that he "definitely" wants to win the competition, saying that wherever he's been he has "won trophies" and declaring: "I hope that my third club [Liverpool] will be another club where I'm going to win a trophy."
He said that he wants to win wherever he goes, including on the international stage with Ivory Coast although he's now retired, repeating that he wants to win something for the Reds with his future at the club uncertain and his contract running out in the summer.
Touré says Reds face tougher game than last time
This is just the second meeting between the two teams since Jürgen Klopp took over at the helm five months ago, with the first fixture resulting in a comprehensive 4-1 win for the Reds at the Etihad Stadium.
But Touré is under no illusions that Sunday's fixture will be a different, and a tougher, game than that night in November.
"It's going to be a different game," said the centre-back, who says he was "not expecting that score" when they last played each other.
"But, like I said," he added, "It is a final and the team who will want to win on the day, who will be prepared well and who will want to [give everything] for the game is going to win."
