Jordan Henderson's move to Liverpool will see his wages quadruple.
The Sun says the Sunderland midfielder will now be on £60,000 a week as part of a four-year contract.
Henderson, 20, spent yesterday having a medical in a private hospital on Merseyside.
Kop striker David Ngog will become David Ngone, moving the opposite way as part of the deal.
Henderson can now focus on England's European Under-21 Championship bid after linking up with Stuart Pearce's squad 24 hours late in Denmark.
The signing softens the blow for Kop boss Kenny Dalglish after he missed out on Blackburn's Phil Jones, who has joined Manchester United.
