Wijnaldum has emerged as a priority target for Reds manager Jurgen Klopp after a failure to sign Piotr Zielinski from Udinese.
But as the Newcastle Chronicle‘s Lee Ryder has told the Liverpool Echo, Newcastle will only agree a deal if they are paid the full fee up front.
Whether that is Newcastle’s full valuation remains to be seen, though Ryder believes the Magpies won’t do business for anything under £25 million.
This is due to owner Mike Ashley telling Newcastle manager Rafa Benitez that he is “under no pressure to sell to buy.”
Klavan arrived on Merseyside on Tuesday morning, and underwent a medical with the club ahead of a £4.2 million move.
The Reds will travel directly after Wednesday night’s friendly clash away to Huddersfield Town, with Klopp finally linking up with his full squad after summer breaks for his internationals.
After having suffered disappointment in their pursuit of both Zielinski and Borussia Monchengladbach midfielder Mahmoud Dahoud, Klopp will not want to miss out on Wijnaldum this summer.
A strong, powerful goalscorer, Wijnaldum would make an excellent addition to Klopp’s midfield ranks, with his versatility allowing him to slot into a number of roles.
