The Robins were the recipients of the talented 18-year-old striker's services in the summer after agreeing a season-long loan with the Blues.
Abraham told the Daily Mail that a meeting with City's promising manager swiftly helped him make up his mind on a move to Ashton Gate.
“The gaffer got mine and my parents' trust from there," he said.
“It was more of a family decision. We sat at the kitchen table and he outlined what I could expect.
“He told me that it's a young side that can push for promotion and if I keep working hard I will get games."
Abraham has starred for the Robins early in this season-long stint, scoring 10 goals in 13 appearances.
