Salomon Kalou's agent has confirmed that his client is open to joining Liverpool this summer.
Schalke are also keen on Ivory Coast international Kalou, whose Chelsea contract expires this summer, and agent Rodger Linse is ruling nothing out.
"There are conversations going on, and of course when that is happening then you must be careful what you say," Linse told the Liverpool Echo. "Liverpool can speak for themselves, and Schalke can speak for themselves. That is fine.
"Of course Liverpool is a very big club, in terms of support and in terms of history. It is definitely positive to hear that a big club like them are showing an interest in Salomon, though it is too early to say anything definitive at this stage."
He added: "He has been very happy at Chelsea. He is a player with ambition, and he has managed to satisfy a lot of those ambitions over the last few years.
"He never quite made it to be a guaranteed starter with Chelsea, but his statistics were always good, and he won lots of trophies there. In many ways, it will be difficult to find a better place to be, but he is open-minded, and would be happy to continue in England if the right club comes in."
