Barcelona debutant Dani Olmo struck a late winner to steal a 2-1 comeback victory at Rayo Vallecano on Tuesday, as the LaLiga leaders continued their perfect start to the season with a third consecutive win.

Rayo dominated proceedings in the first half and took the lead with a strike by Unai Lopez in the ninth minute, but Barca were livelier after the break, with Pedri levelling from a counter-attack in the 60th minute.

Olmo, introduced as a substitute for his first outing since leaving RB Leipzig, scored the winner with a curling strike in the 82nd minute, snatching Barca a deserved win to maintain their momentum.

Barcelona top the standings on nine points from three games, two ahead of second-placed Villarreal, while Rayo are eighth on four points.

Data Debrief: Olmo impresses on maiden bow

Olmo is the first player to score on his debut for Barcelona in LaLiga away from home since Sandro Ramirez in August 2014 against Villarreal.

Yet a familiar face paved the way for the leveller, too, with Raphinha setting up Pedri for his 17th assist in 67 LaLiga outings.

Since his arrival at Barca in the 2022-23 campaign, only Antoine Griezmann (24) has provided more assists than the Brazilian in the competition (also 17 for Alex Baena).
