Southampton are close to the £7m signing of forward Ben Brereton Diaz from Spanish side Villarreal.
The 25-year-old is expected to move to St Mary's to end his short spell in Spain.
He moved to the Yellow Submarine last summer after leaving Blackburn, following five years at Ewood Park.
But the Chile international struggled to make a consistent impact at the La Liga club. He failed to score in 20 appearances for Villarreal, although just six were starts.
Brereton Diaz joined Sheffield United on loan in January and scored six times in 14 Premier League appearances for the Blades, but was unable to stop their relegation from the top flight.
