Liverpool have to pay a potential £22.1million in add-on fees for completed transfers, Football Insider can reveal.

The club recently announced their turnover had soared to £533million for the year ending 31 May 2019 with a pre-tax profit of £42m secured.

Analysis of the accounts shows that the runaway Premier League leaders still have some multi-million pound top-up payments to make for some of their signings in recent years.

Point 22 explains that under the terms of certain contracts “for the acquisition of players’ registrations”, future transfer fees of up to £22.1m are payable.

This is a £16m reduction on the 2017-18 season, when Liverpool owed up to £38.2m in add-on costs for signings.

The accounts do no specify the amounts of individual signings.

But Football Insider has learned that one of the future payments facing the bill is for the club-record signing of Virgil van Dijk.

The reigning PFA Footballer of the Year, 28, joined from Southampton in January 2018 for an initial fee of £70m.

Should Van Dijk play 150 matches for Liverpool – he has made 113 appearances to date – a further £4m must be paid to the south-coast club.

The top-up costs for signings are in addition to guaranteed transfer fee payments, which are staggered across various payments and accounting periods.

During the period reported, Liverpool lifted their sixth European Cup as well as finished second in the Premier League with a remarkable tally of 97 points.

They are set to go one better when this season is finally completed after all but sealing the league title before the recent suspension of sport across the globe.
