Pedro Porro is reportedly set to leave Manchester City after Sporting Lisbon triggered the release clause for the 22-year-old.
The Spanish international joined the Citizens in 2019, but in the three years since his arrival, he has not made a single appearance for the club.
After spending a season with Real Valladolid, Porro joined Sporting on a two-year loan deal in 2020, which included an option to buy.
Following an impressive spell with the Portuguese giants, which has included a league title and a Portuguese League Cup win, Sporting are reportedly set to buy the 22-year-old.
According to transfer expert Fabrizio Romano, Sporting have triggered the €45m (£38.6m) release clause for the right-back, with the player expected to sign a three-year deal.
Despite losing Porro, City will reportedly have the option to buy the defender back for €20m (£17.1m).
Porro has made 33 appearances for Sporting this season, chipping in with four goals in that period.
