Some City fans may wish the Italian had stayed put.
But England star Johnson said: "I don't think they will miss Balotelli. I'm not being disrespectful to the guy but everyone knows what he's like.
"On his day, he can be a great player... but City have got great players who do it a lot more often and score more goals than him."
Johnson, 28, also faced Balo in England's Euro 2012 quarter-final against Italy.
And the Anfield defender added: "We all have our faults but Mario let his side down a lot with silly red cards and stuff like that.
"He's a great player but we didn't see that enough. Personally, I won't miss him. He was probably more famous for things he did off the pitch than what he did on it."
