The Swede has always been a Reds supporter.
And he told the Sunday Times: "This Liverpool team have everything, and the best thing they did is buy [Virgil] van Dijk.
"You can attack with a lot of people because he will always sort out one against one at the back. If you have Van Dijk you can do whatever you want, he is out of this world.
“A couple of years ago, City were extremely good but I don't think you can compete with the same hunger year after year, changing not too many players. [Pep Guardiola] is intense.
“I have a good example of that. Arrigo Sacchi slowly killed the players [at AC Milan], he asked too much. I got Ruud Gullit in Sampdoria, coming from Milan, and we talked about Sacchi. He told me that one day he, [Frank] Rijkaard and [Marco] van Basten went to see [the AC Milan owner Silvio] Berlusconi: 'Us or him, Berlusconi, you have to choose, not one day more.'"
