Liverpool had previously offered £110 million for Isaac, but was rejected by Newcastle, who wanted more transfer fees.

According to the Guardian, given that Newcastle quickly rejected Liverpool's offer, the Reds believed that it would be futile to make a offer again before the transfer window closed on September 1. However, the £110 million offer they offered to the player who wanted to leave the team remains valid.

Isaac has informed the club that he hopes to explore his future this summer, with Liverpool being his first choice and he has been training at his former club Real Sociedad this week. It is not clear whether Isaac has obtained Newcastle United's permission. The two parties have made no progress in renewing the contract.
