West Brom face a battle to keep hold of Nacer Chadli.
The Belgium midfielder has been linked with Everton since last week's row with manager Tony Pulis.
The Telegraph says Swansea also will pursue a swoop for Chadli if they lose Gylfi Sigurdsson to Everton.
The Swans would consider a £15 million move for the West Brom forward.
Chadli scored five goals in 32 games last term.
