Barcelona are plotting a move for Sergio Reguilon and view the Spurs left-back as a potential alternative to top transfer targets Marcus Alonso and Cesar Azpilicueta, according to reports.
Chelsea, who missed out on signing both Jules Kounde and Raphinha because of late £55million and £56m bids from Barcelona, have made life difficult for the Spanish giants in their pursuit of Alonso and Azpilicueta.
Both defenders have expressed interest in teaming up with Xavi in Catalonia, but the Blues are eager not to offload the pair to their transfer rivals.
