The Spanish international represented Barca between 2008 and 2011, before making the move to Benfica and latterly Celta, via a loan spell at Granada.
The 29-year-old's form over the last couple of seasons led to suggestions that his former club would look to re-sign the striker in January, but the move failed to materialise and Luis Enrique's side are unlikely to return with a bid.
"I'm not mad or anything with Barca, these are things that happen. I am a person who is not angry and I always try to get away from these things," Nolito told Weloba.cat.
Nolito scored 12 times in 28 appearances for Celta during the 2015-16 campaign.
