Alba said he is wary of the threat PSG pose both in attack and defence but that his teammates are keen to "correct" the mistakes made against AC Milan in the first leg of the round of 16.
"PSG are a complete side who are defensively strong and have quality attackers," UEFA.com quotes Alba as saying.
"We have learned so much from the last round and must correct our mistakes. PSG are obviously very difficult opponents but the draw looks good to me."
Barca are back in league action on Sunday and face Rayo Vallecano.
