Barcelona have identified Arsenal defender Hector Bellerin as a late transfer target, according to a report.
Ronald Koeman is on the lookout for a new right-back, with Emerson close to agreeing a move to Tottenham Hotspur.
Sergi Roberto is currently being used in midfield, meaning that 22-year-old Oscar Mingueza and 20-year-old Sergino Dest are the Dutchman's only other options on the right hand side of defence.
According to Sky Sports Italia, Bellerin could be the man to plug the gap, with the Spaniard keen to leave Arsenal before the end of the transfer window.
Bellerin started on the bench for the Gunners' opening Premier League game against Brentford, but has not even been included in the matchday squad for their last two fixtures.
The 26-year-old was in Barcelona's academy from the age of eight until he joined Arsenal at 16; he has made 239 appearances for the North London club.
