#4 Jose Luis Gaya - Valencia
The 23-year-old has been a phenomenon with the Valencia side and is a product of the Valencia youth academy. Just like the Barcelona star, Gaya has been an asset for Valencia. A quick, agile and intelligent playmaker from the flank, Gaya's abilities extend far beyond those of other young left-backs.
Hisplaymaking abilities and extremely accurate crosses have earned him a lot of attention from some of the top football clubs in the world, and that includes Manchester United, Chelsea and Bayern Munich.
As mentioned, a move to Camp Nou won't be an easy one for the Spaniard, but his will to play for a club like Barcelona can get him a place in their squad. The 23-year-old's charisma is what Barcelona would truly require for replacing Alba, and Gaya surely has it. After all, Valencia is known for delivering some of the best world-class prospects in football.
