Aston Villa will buy Scott Sinclair from Manchester City this summer for £2.5 million.
Sinclair, 26, has spent the last four months on loan at Villa Park and, as part of the terms of the deal, when Villa avoided relegation, they were committed to signing the former Swansea and Chelsea winger on a permanent deal.
FA Cup finalists Villa became mathematically safe on Saturday, despite losing 6-1 to Southampton, as a result of Hull's 2-0 defeat to Tottenham.
The transfer will end Sinclair's disastrous three-year spell at City, in which he began just three games and failed to score a goal.
He was bought for £6.2 million on the final day of the 2012 summer transfer window but struggled to make an impact under both Roberto Mancini and Manuel Pellegrini.
Sinclair, who was loaned out six times during his spell at Chelsea, joined West Bromwich Albion last season but only began four league games in an injury-hit spell at the Hawthorns.
He has scored three goals for Villa, his first since leaving Swansea, but has not started since the 1-0 defeat to his former club in March as manager Tim Sherwood has changed system to use a diamond midfield.
But former Tottenham manager Sherwood hinted Sinclair would return to the starting XI if he uses a different shape, telling reporters: "It's horses for courses at the moment. That's the way we're choosing to play. We may well change. I think if we go back to wide players then Scott will be an automatic choice to play there."
Sinclair is the third on-loan City player whose move to another club will become permanent in the summer along with Alvaro Negredo, who is at Valencia, and Matija Nastasic, of Schalke.
