Paris Saint-Germain capped a busy transfer window with the loan signing of highly rated left-back Nuno Mendes from Portuguese champions Sporting CP, with Pablo Sarabia moving in the other direction.
Mendes joins PSG on a season-long loan, while the Ligue 1 giants have the option to buy the Portugal international at the end of the season.
The 19-year-old had previously been linked with the likes of Manchester City and Liverpool, but he has made the move to PSG alongside fellow recruits Lionel Messi, Sergio Ramos, Gianluigi Donnarumma, Achraf Hakimi and Georginio Wijnaldum.
A product of Sporting's famed youth academy, Mendes played a key role as the club ended their 19-year title drought last season.
The teenager amassed a total of 47 appearances across all competitions, scoring once and tallying three assists for Sporting, who also won the Taca da Liga in 2020-21.
Last season, Mendes ranked fourth in the league in expected assists (3.44), third in duels won (186) and second in dribbles attempted (88).
Mendes made two Primeira Liga appearances this term, leaving an unbeaten Sporting side second in the standings and two points adrift of rivals Benfica through four rounds.
He joins a PSG team that standing two points clear at the top of Ligue 1 with four wins out of four and craving a first Champions League triumph.
Spain midfielder Sarabia will spend the remainder of the season on loan with Sporting.
The 29-year-old has scored 22 goals and provided 12 assists for PSG since his move from Sevilla in 2019.
