Premier ​League clubs are facing demands for ever higher transfer fees and for players’ wages to be paid in euros because of the collapse in the value of the pound since the Brexit vote.

As sterling fell this week to its lowest value since Britain emerged from the financial crash, the consequences for top-flight clubs have been laid bare by the haggling over the future of Ajax’s Davinson Sánchez.

The Dutch newspaper De Telegraaf reports that as negotiations between Tottenham Hotspur and Ajax have dragged on over the 21-year-old defender, Ajax have been insisting on increasing their asking price to reflect the day-by-day fall in the value of the pound.

The newspaper reports: “Spurs will have to pay more by the day. Compared with the end of the previous season, the pound is 6% lower. On the sum that Ajax want (€50m), that’s already a difference of €3m. And the expectation is that the free fall will not stop.”

It is claimed by the newspaper that ​because of this “complication”, Tottenham are seeking to speed up the signing of the Colombia international, but that Ajax are happy to slow the pace of negotiations down, with Chelsea and Real Madrid showing some interest. Officials from Tottenham were said to be in Amsterdam on Monday.

The De Telegraaf article further reports that Dutch players already in the ​Premier League have been detrimentally impacted by the fall in the pound against the euro. “Players who have put their salary in pounds may end up earning maybe 10% less,” the paper said. To avoid a salary cut, it is claimed Dutch players are increasingly insisting on their salaries being paid in euros.

On Tuesday, a pound bought only €1.0954, an eight-year low. The last time a pound bought so few euros was in October 2009 when the UK economy had recently emerged from one of the deepest recessions in its history. Last week Morgan Stanley analysts forecast that by early 2018 the currency could fall below parity for the first time.

One positive for clubs who do well in Europe, however, is the pound’s collapse has made winning euros in competitions all the more valuable. In 2016 Manchester City, who reached the semi-finals of the Champions League, earned €83.8m from Uefa in prize money.

Before the referendum in June last year, the football industry voiced its concerns about the impact of Brexit on the Premier League.

Following the result, Arsenal’s Ars​ène Wenger, said he feared the game in England would suffer lasting damage. “It worries me, it shocks me too,” ​the Frenchman said. “Nobody knows how exactly this is going to translate into a practical plan. Nobody really knows where we are going. The players will see their wages come down a bit and the competition with Germany, for example, will be stronger.”
