Arsenal have reportedly informed Juventus to pay £18m if they wish to sign Aaron Ramsey six months early.
The Wales international is due to join the Serie A giants at the end of the campaign when his Emirates Stadium contract expires.
Juve are expected to make a formal announcement about the free signing in the coming days, but the Italian club are believed to have been offered the chance to fast track the deal.
Gazzetta dello Sport reports that Juventus are eager to get the 28-year-old on board as soon as possible, but they are unlikely to match Arsenal's valuation for a player in the final stages of his contract.
Should Ramsey quit North London this month, Unai Emery will have money to reinvest back into his squad before the end of the January transfer window.
