Everton's Lucas Digne is set to move to Aston Villa after the clubs struck a deal worth up to £25m for the full-back.
In a separate development, Everton have inquired about Aston Villa winger Anwar El Ghazi.
Villa have tracked 28-year-old Digne since he fell from favour with Everton boss Rafael Benitez this season.
Meanwhile, Villa have completed the loan signing of Barcelona playmaker Philippe Coutinho.
The deal for the Brazil international includes an option to buy the 29-year-old for £33m at the end of the season.
"Philippe Coutinho arrived at Bodymoor Heath on Tuesday afternoon to complete his move to Aston Villa," said the Midlands club.
