Barcelona hopes to sign a replacement for Sergio Busquets in January.

Barca, as previously revealed by ESPN, sounded out deals for Real Sociedad's Martin Zubimendi and Wolverhampton Wanderers' Ruben Neves in the summer as possible options in case Frenkie de Jong moved to the Premier League.

Zubimendi and Neves remain on Barca's radar, sources have confirmed. The former recently signed a new contract with Real Sociedad, although his release clause remained fixed at around €60 million.
