Liverpool broke the bank last month to sign Dutch centre-back Virgil van Dijk for a club record £75million.
The fee is also the most expensive ever spent on a defender, and The Sun are claiming the Merseysiders are ready to splash £40million on Stoke City Jack Butland come summer.
Completing the deal will see the Reds break the current £35million world record fee paid for a goalkeeper – Manchester City’s Ederson, and it seems manager Jurgen Klopp is willing to go all out in order to fortify his defence.
The goalkeeping duo of Loris Karius and Simon Mignolet has failed to impress, and the German boss sees the Stoke shotstopper as the perfect option.
The 24-year-old England international is in contention for a starting spot for the Three Lions at the summer World Cup, and has already proven himself at the topflight with the Potters.
Arsenal are also keen on Butland, with manager Arsene Wenger planning on replacing 35-year-old Petr Cech with a quality long-term replacement.
Chelsea and Manchester United have also been linked with the Englishman, and both sides are said to be preparing to enter the race should they lose Thibaut Courtois and David Degea respectively at the end of the campaign.
Butland has everything it takes to improve Liverpool should a move go through, but the Reds will have to beat fierce competition to land him.
