Real Betis are hopeful of signing Sporting CP and Portugal international midfielder William Carvalho in a €20m, according to reports.
Numerous Spanish media outlets cite Portuguese daily Record that Los Verdiblancos have made a move for the central midfielder.
Carvalho is one of a host of players at Sporting to attempt to cancel their contracts but a compensation package is expected to be due for the Portugal international.
The 26-year-old would fill a void left by the outgoing Fabian Ruiz and provide competition for Javi Garcia in the holding midfield role.
The Portuguese club are in crisis, with controversial President Bruno de Carvalho voted out by supporters.
He had appointed Sinisa Mihajlovic as Coach, but the Serbian was sacked after just nine days.
