Firpo, on the other hand, recently swapped Camp Nou for Elland Road, having spent two lackluster seasons with Barcelona. With no proven entity to provide cover for an aging Jordi Alba, the 26-time Spanish league champions are reportedly eyeing the market for a potential successor.With the constant surfacing of such rumors, Jordi Alba's time at his boyhood club seems to be marching towards an inevitable end. Keeping his invaluable contributions in mind, let's take a look at five players who could take Jordi Alba's place at Barcelona:#5 Robin Gosens (Atalanta)Portugal v Germany - UEFA Euro 2020: Group FOne of the many breakout stars of an exciting Atalanta side, Robin Gosens has experienced a sudden rise to prominence. While Gosens had been slumming it out in the Dutch league for many years, his transfer to Atalanta really put the German wing-back on the map.An exceptional Euro 2020 campaign, where he single-handedly dismantled the Portuguese side, shot the 27-year-old to superstardom, attracting multiple suitors. Due to his remarkable offensive contributions, similar to Jordi Alba's output, Barcelona have emerged as a potential destination for the German.UtdDistrict@UtdDistrict🗣 Amad: "The [Atalanta] wingers, [Robin] Gosens and [Ruslan] Malinovsky, are strengths of theirs, they will give you a difficult game.

With Barcelona clearly eyeing him as a possible replacement for Jordi Alba, Atalanta are holding on to him in an attempt to make maximum profit. While a recent long-term injury might sway his suitors away, Gosens remains a top-class potential option on the left side of the defense for Barcelona.#4 Juan Miranda (Real Betis)Miranda recently joined Real Betis from BarcelonaFollowing an impressive loan spell with Real Betis in 2020, Juan Miranda joined Los Verdiblancos on a permanent transfer this summer.
