The Reds also expect to complete the signing of Dutch under 21's international Ryan Babel from Ajax after upping their offer to £12m.
"I had heard that there were some stories on the internet but that happens quite often. This [Liverpool's interest] is serious news to me," said Babel.
"I haven't thought about a transfer for a minute, I will do that soon though. That such a big club is interested is of course very nice."
