Swansea City have completed a deal to sell midfielder Roque Mesa to Spanish La Liga side Sevilla.
The 29-year-old Spaniard had been on loan at the La Liga side since last January.
Mesa has now completed a permanent move on a three-year deal for an undisclosed fee, although it is thought that could be in the region of £8m.
He signed a four-year contract with Swansea in July 2017 in an £11m switch from Las Palmas.
Mesa struggled to settle in south Wales and made just nine Premier League starts before heading back to Spain midway through last season, signing a loan deal with Sevilla until the end of the campaign.
That deal is thought to have included a buy-out option which, after a period of discussion, Sevilla have finalised with Swansea.
Mesa joins midfielder Ki Sung-yueng in leaving the Liberty Stadium following their relegation from the Premier League, with the South Korea captain opting to leave at the end of his contract.
Winger Kenji Gorre has joined Portuguese club Nacional after his Swansea contract expired this summer.
The 23-year-old Dutchman made one Premier League appearance for the Swans, coming on as a late substitute in the final-day defeat at Crystal Palace during the 2014-15 season.
Last week Swansea confirmed the sale of goalkeeper Lukasz Fabianski to West Ham United in a deal thought to be worth an initial £6m.
West Ham are also keen on signing centre-back Alfie Mawson. The Hammers have had a bid rejected for the 24-year-old, with the offer falling below Swansea's £20m-plus valuation of the defender.
