According to reporter Ben Jacobs, even though the official offer was rejected by Newcastle, Liverpool is still confident of signing Isaac.
Ben Jacobs wrote on social media: "Latest news: Newcastle has rejected the official offer from Liverpool for Isaac, as David Ornstein reported."
"Previously, Liverpool said they were willing to pay about £120 million to sign Isaac. This time, the official offer from the Reds was proposed by Richard Hughes. Despite the rejection, Liverpool's offer still shows their optimism about the introduction of Isaac, and the players themselves are pushing for the transfer."
