The 24-year-old has admonished the Spanish coach for using him as a winger during their time together at the Stadio Olimpico
The once-capped Spain international attacker said that the Barcelona boss played him out of position while the Giallorossi's former sporting director "disrespected" him.
The 24-year-old came through the youth team ranks at Camp Nou before moving to the Stadio Olimpico in the summer of 2011 for a fee of €12 million.
However, the forward failed to justify his price tag over the course of a disappointing debut season in Italian capital and spent another frustrating campaign on loan to AC Milan before returning to Barca.
Bojan believes that he could have flourished at Roma had he been properly managed.
“I'm finally being played in my own role, unlike in Italy,” he told the Corriere dello Sport.
“I'm a striker. At the most I can play just behind the forwards, but not as a winger.
“Luis Enrique didn't know me well enough, I spent a complicated year working with him.
“Later, I wasn't part of the plans of the new coach [Zdenek Zeman].
“And I had some problems with Baldini. On one day he was telling me to stay, on another that I may be sold. He disrespected me, that's all.
“But I'm grateful to Roma - they were the first club who opened their doors to me after Barcelona.
“It's a shame that our paths should have parted the way they did.”
Bojan also dismissed the suggestion that Francesco Totti cast too large a shadow over the Roma attack, insisting that he had no problem with the iconic captain being the fulcrum of the front line.
"On the contrary," he added. "When you play with him you're the one who has to adapt, not the other way round. He's outstanding."
