Swedberg came through Hammarby's academy in Stockholm before joining Celta as a teenager, and has developed steadily in Galicia into a genuine match-winner.
A left winger who operates naturally off his right foot, he combines sharp movement into space, a confident first touch and the vision to pick out team-mates in dangerous areas — a profile that suits Giráldez's attacking system perfectly. His four LaLiga goals this season include a brace in Celta's stunning 2-0 win at Real Madrid's Bernabéu in December, a result that announced him to a wider audience and earned him the Best Under-23 Player award for that month.
The Swede is also Celta's top scorer in the Europa League this season with four goals in the competition, contributing as the Galicians have beaten Nice, Lille and PAOK on their way to the quarter-finals — the club's deepest European run since a memorable semi-final appearance in 2017. They face Freiburg in the last eight, with the first leg in Germany on Thursday, and Swedberg's form makes him central to their hopes. Captain Iago Aspas is absent for the trip, which places still greater attacking responsibility on the young Swede.
What makes the Swedberg story compelling is the trajectory. In his first two seasons at Balaídos he made a combined 19 appearances. Now he is an indispensable part of one of LaLiga's most attractive teams, operating in a squad that also features Ferrán Jutglà, Ilaix Moriba and the ever-present Aspas. Born in Stockholm in February 2004 and trilingual after a childhood spent partly in Valencia, Swedberg looks every inch a player on the cusp of a major move.
For now, Celta and Giráldez will hope he stays focused. There is a European quarter-final to win first.
