Having only completed three signings so far, FC Barcelona coach Ernesto Valverde has hinted at another possible arrival after pointing out a 'problem' area in the side.
Click through the mini-gallery to see the left-backs linked with Barcelona.
Frenkie de Jong, Neto and Antoine Griezmann have completed moves to the Camp Nou this past month, while the club have also been linked with Paris Saint-Germain's Neymar.
With the attack fully stacked following the arrival of Griezmann, Valverde has now identified the left full-back position as a worry.
Jordi Alba remains first choice, but the club are now looking to find cover for the Spain international while Real Betis' Junior Firpo and Stuttgart's Phillip Max have been linked.
"It is possible that we bring someone on," Valverde said on Friday, according to Marca.
"It's true that in that position we had problems last season.
"We are open to signing players until the end of the market."
