Vida is being targeted by at least four Premier League clubs since helping Croatia to the final of the World Cup.
Arsenal, Everton and West Ham United are all interested in the centre-back, though the Reds appear to have won the race.
Turkish outlet A Spor suggests that Liverpool must now settle on a figure for Vida after the former Dynamo Kiev man agreed to a move.
Due to the growing interest since the World Cup finished earlier this July, the 29-year-old is now believed to be valued in the region of £22m.
