Speaking on the Stick to Football podcast, Keane said: I don't know what the big deal is, I give Erling Haaland praise every week, I give Manchester City praise, and I think he's an amazing striker.
"But his general play is that of a League Two player. And I'm glad you are not agreeing with me, I don't expect people to agree with me.
His general play, week in, week out is nowhere near good enough. As a goal scorer and a striker, the best and I said that. His link-up play, the way he lays the ball off, sometimes the options he gives his teammates or the options he doesn't give them as a striker and a goal scorer the best in the world, but his other play is that of a League Two player.
"The game against Arsenal was tough because they did well to contain the whole game, but in general, I don't think what I said was a big deal.
"He's a young player and he will improve, and I guarantee you that Pep Guardiola sits with his staff on everything and say that he needs to do more, specifically when he's not getting of chances or loads of goals."
