The Italian is unhappy with his Northern Irish counterpart.
However, a successful loan stint with the Black Cats saw Rodgers retain his services for the following season, though the Italian started just three league outings.
The Northern Irishman then let Borini join Sunderland on a permanent basis last July, and he admits that he still feels somewhat bitter toward Rodgers - who has since been sacked - for a lack of chances.
"The move from Roma to Liverpool was very negative," he told Italian outlet DiMarzio.com.
“I expected more consideration from Brendan Rogers but I have no regrets at returning here. Now I feel fit and I'm scoring goals.”
He might not be at a bigger club than Liverpool, but at least he is playing. Borini has started 14 Premier League games under Sam Allardyce, appearing from the bench on four occasions.
He could yet get relegated with the club, though, as Allardyce's men sit 17th in the table, safe only on goal difference from Norwich City in 18th as it stands, with Newcastle a point back.
