Carragher was responding to Arteta's statement that Arsenal's 1-1 draw with Manchester City showed they were a dominant team, despite playing with a "handbrake" on. Arteta argued that dominance and playing with a handbrake are two different things, and that Arsenal's stats and players, including their goalkeeper, justify their dominance.
Carragher disagreed, saying that Arteta's reasoning didn't add up. He pointed out that Arteta started by saying they have the most attacking goalkeeper in the league, but then mentioned their full-backs, which Carragher thought were actually centre-backs. He also questioned Arteta's mention of Martin Zubimendi, a creative player, and a wide player playing centre forward, which he thought was an attempt to argue against the idea that Arsenal are an offensive team.
Carragher expressed his concern that Arteta might be doubling down on his original statement to his coaching staff and players, but he didn't think the evidence supported Arteta's claim that Arsenal are a dominant, attacking team.
