Barcelona are reportedly looking to sign a replacement for Sergio Busquets, who could leave the club at the end of the season.
Busquets has registered 18 goals and 43 assists in 693 appearances for Barcelona, where he has won numerous honours, including eight La Liga titles and three Champions League trophies.
While the Spain international has started 12 of Barcelona's 15 competitive games this term, his performances against Inter and Real Madrid came under scrutiny.
With his contract set to expire next summer, Busquets is widely expected to leave the Catalan giants at the end of the current season.
According to ESPN, Barcelona have already begun their search for potential replacements as they look to recruit a new midfielder in the January transfer window.
Barcelona were linked with Real Sociedad's Martin Zubimendi and Wolverhampton Wanderers' Ruben Neves in the summer, and the pair remain viable options.
The report suggests that Ajax midfielder Edson Alvarez is on Barcelona's radar, while PSV Eindhoven's Ibrahim Sangare and Chelsea's Jorginho are also under consideration.
