Swansea are poised to sign Ivory Coast striker Wilfried Bony from Dutch side Vitesse Arnhem on Wednesday, Press Association Sport reports.
Bony, 24, has appeared on Twitter posing with a Swans shirt alongside club chairman Huw Jenkins, fuelling speculation a £13 million transfer is set to be completed.
Such a deal would smash the Welsh club's previous transfer record, which was 5.55million, which went to Valencia last season for winger Pablo Hernandez.
Bony 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 Premier League last term, have made this summer.
