Keane joined Celtic on a six-month loan deal on Monday.
“You have to be able to live with the pressure. It’s fantastic news for Celtic to get a striker of his quality. From what I understand, he is a great fan of Celtic as well and that’s very important. He will know how important it is for the fans to play well,” said Larsson to BBC Radio Five Live.
“It’s not for me to recommend whether he stays on or not after this season. If he does well – which I’m absolutely sure that he will – then there are not a lot of pleasures that are better than being up there.
“I know he has played for other big teams in the past but this is one of his boyhood dreams coming to play for Celtic. I’m all for it that he stays up there because Celtic need all the good players they can have.”
