Liverpool could be forced to increase their bid for Adam Lallana as a chunk of the transfer fee will go straight from Southampton to the midfielder's former club AFC Bournemouth.
Brendan Rodgers does not want to budge over the £20m already tabled for Lallana.
But with Championship side Bournemouth set to pocket up to 25% of whatever fee is agreed between the two Premier League clubs, Southampton are holding out for a higher sum and could look to hike their asking price to mitigate handing over a quarter of the transfer cash.
Premier League runners-up Liverpool would like to have the deal wrapped up by the time England jet out to Brazil for the World Cup next month.
Tying him down would prevent Manchester United and Tottenham Hotspur, both admirers of the forward, from potentially hijacking the move.
But talks could hit a snag if Saints raise their valuation of the 26-year-old club captain.
Lallana and his family moved to Bournemouth from St Albans when he was five. The youngster was soon invited by an ex-Bournemouth pro to join the AFC Bournemouth Centre of Excellence.
His potential was spotted by a scout from Southampton who snapped up Lallana in September 2000 when he was still only 12-years-old.
An independent tribunal later ruled that the Cherries, who finished 10th in the Championship last season, should receive a compensation from Saints as well as a potentially lucrative sell-on fee. It is that clause that could inflate his value delaying a dream move to Anfield.
