Southampton are poised to announce Russell Martin as their new head coach having confirmed Rubén Sellés will depart after taking charge against Liverpool on Sunday, their final game of the season.
A compensation package worth upwards of £400,000 is thought to have been agreed with Championship Swansea City where Martin, the former Norwich defender and captain, has won admirers across the past two seasons.
Relegated Southampton struck a deal with Martin after he did not travel to the United States as planned for talks with the Swansea owners.
Enzo Maresca, who works alongside Pep Guardiola at Manchester City, was also earmarked as a candidate for the job.
