Bournemouth are signing Argentina centre-back Marcos Senesi from Feyenoord.
Talks are advancing over a £12.6million fee plus add-ons for the 25-year-old, who is in the last year of his contract.
The defender would be a welcome addition for Cherries manager Scott Parker, who has spoken negatively of Bournemouth's situation after a frustrating summer in the transfer market.
The Cherries have only made three signings in the transfer window so far, luring Joe Rothwell, Ryan Fredericks and Marcus Tavernier to the Vitality Stadium.
They are favourites for relegation and Parker had warned fans of the side's situation, with Rothwell and Fredericks both carrying injuries.
