Barcelona are reportedly considering a move for Arsenal right back Hector Bellerin as a replacement for Tottenham-bound Emerson Royal.
Spurs have agreed a £25.7million fee for the Brazilian with the cash-strapped Catalans and are hopeful of pushing through a deal before Tuesday's transfer deadline.
Emerson's departure leaves Ronald Koeman short of options at right back, with just Sergino Dest and Oscar Minguez to choose from due to Sergi Roberto being used in the centre of midfield.
Minguez has also had to fill in at centre back, meaning Dest is the main right back at present.
