Barcelona loaned striker Vitor Roque to fellow LaLiga side Real Betis on Monday after he failed to make an impact in his first few months at the club.
The Catalan giants also loaned centre-back Clement Lenglet to title rivals Atletico Madrid.
Brazilian forward Roque arrived from Athletico Paranaense in January after Barca signed him for around €30 million ($33.5 million) in July 2023.
Roque scored two goals in 16 games for the club as Barcelona watched rivals Real Madrid lift LaLiga and the Champions League.
"Agreement reached between FC Barcelona and Real Betis for the loan of Vitor Roque until June 30 2025, with the option of another year," said Barcelona in a statement.
The Catalan giants confirmed Betis also have an option to buy the 19-year-old.
French defender Lenglet, 29, joins Atletico until the end of the season, after previous loans to Tottenham and Aston Villa.
Barcelona have not been able to register summer signing Dani Olmo with LaLiga yet, owing to their economic difficulties and the league's strict financial rules.
They let Ilkay Gundogan return to Manchester City last week and coach Hansi Flick was hopeful it would give the club enough room to register Olmo, but the playmaker was not available to face Athletic Bilbao on Saturday.
