Tottenham have signed Spanish defender Pedro Porro from Portuguese side Sporting on loan until the end of the season with an obligation to make the deal permanent in the summer, the Premier League club announced on Tuesday.
Financial details were not disclosed but British media reported that Spurs paid around £40 million for the 23-year-old right back.
Porro became the London club's second signing of the January transfer window after they also brought in winger Arnaut Danjuma on loan from Villarreal.
Manchester City signed Porro in 2019 but immediately loaned him to Real Valladolid for one season before he joined Sporting on a two-year loan deal. In 2022, Sporting triggered Porro's buyout clause and signed him on a permanent deal.
Porro joins Tottenham as they look to strengthen the right side of their defence and fight for a top-four spot, with Antonio Conte's side currently fifth on 36 points after 21 games. They next host champions Manchester City on Sunday.
Porro's arrival followed the departure of right back Matt Doherty to Atletico Madrid after the Irish player agreed to terminate his contract with Tottenham.
