The 22-year-old has been linked with a move to Camp Nou after an impressive start to the season at Mestalla, which has earned him a regular place in the Spain national team.
Despite previously saying he wanted to play at Valencia 'for many more years', he has now revealed that he would be interested in a return to Barcelona, having been part of the La Masia youth set-up between 1998 and 2005.
"Any player as a kid dreams of winning things with Barca," Alba said in an interview with Gol Television.
The Spain international has a contract with Valencia until 2013, which may force Los Che to sell him in the summer to prevent losing him for free.
Alba will play against Barca on Wednesday as Valencia take on the Catalan side in the second-leg of the Copa del Rey semi-finals.
