Arsenal are facing a major roadblock in their pursuit of Real Betis star Junior Firpo.
The 22-year-old scored in Sunday's enthralling 4-3 win over Barcelona at Camp Nou.
His exploits have caught the eye of Arsenal's recruitment department, according to The Sun.
However, Manchester City may have the edge over their Premier League rivals as Firpo is represented by Pep Guardiola's brother.
It is understood Firpo has a release clause of £43.5million in his Betis contract, which he penned last season.
Gunners boss Unai Emery is desperate for a left-back with Sead Kolasinac and Nacho Monreal struggling with injuries this season.
