Swansea expect to confirm the signing of Ivory Coast striker Wilfried Bony from Dutch side Vitesse Arnhem within the next 24 hours, Press Association Sport understands.
There is yet to be an official announcement from either club about a deal, but a picture of Bony posing with a Swans shirt alongside the Welsh outfit's chairman Huw Jenkins appeared on Twitter on Tuesday evening.
And it is understood the transfer - thought to be for about £13million, which would be a club record fee paid by Swansea - is set to be tied up around lunchtime on Wednesday.
The Swans' previous record transfer fee paid was £5.55million, which went to Valencia last season for winger Pablo Hernandez.
Bony, 24, was named Dutch football's player of the year for 2012-13, a campaign in which he netted 31 goals in the Eredivisie for Vitesse to become the division's top scorer.
He is poised to become the seventh permanent signing Swansea, who finished ninth in the Barclays Premier League last term, have made this summer.
Jonjo Shelvey, a senior England debutant in October, completed his move from Liverpool last Wednesday, which followed the arrival of three Spaniards - fellow midfielders Alejandro Pozuelo and Jose Canas, both at Real Betis last season, and defender Jordi Amat, recruited from Espanyol.
The Swans have also brought in two teenagers in Slovenian goalkeeper Gregor Zabret and Cypriot midfielder Alex Gogic, while Villarreal's Holland midfielder Jonathan de Guzman has returned to the Liberty Stadium on loan again, signing a season-long deal with the Carling Cup winners as he did a year ago.
