Spanish midfielder Michu is reportedly in South Wales to hold talks ahead of a move to Swansea City.
The Premier League club agreed a fee with Rayo Vallecano earlier this week for the 26-year-old, who is also believed to have been targeted by Manchester United.
It is understood that Michu will sign a three-year deal at the Liberty Stadium after the completion of his medical.
Michu scored 15 goals for Rayo Vallecano last season.
