The Spain international is approaching a decade at Camp Nou and remains a regular for Barca, which has endured another difficult campaign.
He has featured 408 times for the Catalan giants in all competitions since his debut in August 2012 and has helped the club to 15 trophies.
But Alba has come in for criticism of late, with Barca losing to Real Madrid in the Supercopa de Espana semi-finals before exiting the Copa del Rey to Athletic Bilbao.
After impressing in Monday's (AEDT) 1-0 win over Deportivo Alaves, a game in which he led the way for touches (112) and fouls won (four), Alba expressed his frustration.
"I have felt singled out for many years, it is not the first time it has happened to me," he said. "I accept the criticism that there is in this circus. Criticism will always be there, I have assumed it.
"If I play a good game they won't talk about me, if I don't play well like the other day [against Athletic], I admit it, they will kill me. I have accepted it.
"I don't care because I have respect from my team-mates and from all the coaching staff I've had.
"It seems that there are only 'veterans' in Barcelona. There has been talk of veterans for four or five years, and I was 28, damn it. But I've always accepted it."
Alba has started 23 games under Ronald Koeman and successor Xavi this season – only Marc-Andre ter Stegen (27) and Sergio Busquets (29) have done so more times.
No defender has more assists than Alba's four in LaLiga this term, while his 1.62 chances created per 90 minutes is the fourth-best among those to have played more than once.
Responding to Alba's comments following the win over Alaves, Xavi praised the 32-year-old for learning to live with the weight that comes with playing for Barcelona.
"Alba was criticised and he played a great game," Xavi said at his post-match news conference. "At Barca, the shirt is 20 kilos more than at another club."
