According to the BBC, Slot is very eager to recruit Isaac before the start of the new season, but it is not clear whether Liverpool will continue to raise its offer.
Newcastle has rejected Liverpool's first offer for Isaac, with the Magpies estimating the Swedish international at about £150 million, while Liverpool's offer is below that amount. The specific amount of Liverpool's quotation has not been confirmed yet. Newcastle insists that Isaac will not be sold this summer, but this has not stopped Liverpool from showing strong interest in it.
BBC Sports reported in July that Liverpool is considering making an offer of up to £130 million for Isaac.
Isaac did not join Newcastle in his pre-season Asian tour, after he expressed his desire to explore the possibility of a transfer. It is reported that while Liverpool submitted its offer, Isaac was training alone at his old club Real Sociedad, and his future is still full of uncertainty.
