Porto defender Bruno Martins Indi is due to have a medical at Stoke on Wednesday after the clubs agreed a deal, according to Sky sources.
We understand the fee could rise to £13.4m for the Dutchman.
The 25-year-old spent last season on loan at the Britannia stadium, making 37 appearances as the club finished 13th in the Premier League table.
Martins Indi began his career at Feyenoord before moving to Porto in July 2014.
