Ibrahimovic, who joined Manchester United from Paris St-Germain in the summer, insists the row still motivates him.
“I learned a lot from Barcelona, on and off the pitch,” Ibrahimovic told Sky Italia.
“The problem wasn’t with me, it was with him [Guardiola] and he never came to terms with it.
“I don’t know what his problem was with me.
“Before [I joined Barca] he was calling me every day to get me and then all of a sudden the situation changed.
“I’m using it as a positive, not a negative. It is something in the back of my mind.
“It is the past and I am someone who looks to the future and the future is in front of me.”
