Five and a half years on from last appearing competitively for Barcelona, Dani Alves was named in their starting line-up on Wednesday.
Dani Alves was handed his second debut for Barcelona's Copa del Rey clash with Linares Deportivo after being officially registered by the LaLiga club.
The 38-year-old re-joined Barça on a free transfer in November following his departure from Sao Paulo over a contractual dispute.
He featured in a friendly draw with Boca Juniors in Saudi Arabia last month but could not play competitively until the LaLiga registration window opened on Monday.
Barcelona announced on Wednesday that Alves' registration had been sanctioned and he was part of their squad for the round-of-32 contest.
Alves returns
Alves slotted straight into the starting line-up at Estadio de Linarejos in a side that also included fellow experienced players Neto, Sergio Busquets and Jordi Alba.
Brazil international Alves made 247 appearances for Barça during his first eight-season spell at Camp Nou, the most recent of those games coming in May 2016.
He played his part in 95 clean sheets, had 78 goal involvements (64 assists, 14 goals) and created 377 chances en route to winning 23 trophies, including six LaLiga titles and three Champions League crowns.
Injury issues for Xavi
Copa del Rey holders Barça named Ousmane Dembélé among their substitutes against lower-league opposition Linares after the forward returned a negative coronavirus test. Barcelona went on to win the game 2-1, with second half goals coming from Ferran Jutgla and Ousmane Dembélé.
Sergiño Dest, Sergi Roberto, Luuk de Jong, Philippe Coutinho, Pedri, Memphis Depay, Ansu Fati, Martin Braithwaite, Ferran Torres, Gavi, Ez Abde and Alejandro Balde were all ruled out of the cup clash.
