"I was ready to commit my future to the club. All I wanted were talks about a new contract, but each time we were due to sit down, the club postponed it. I was fobbed off," The Sun quoted Song, as saying.
"I wanted a new five-year contract at Arsenal. In the end I got one, at Barcelona," he added.
Song, 24, revealed how he wanted to stay for life at Arsenal, but was cold-shouldered by officials at Emirates every time he tried to arrange talks over his future,
He claimed that he was distraught when he read stories from "club sources" claiming he had a bad attitude and was constantly late for training.
"I had been trying for eight months to start talking about a new long-term deal, but the club kept postponing me all the time, saying 'You have three years left'. I'm really upset. These accusations are hurtful, they are slurs on my character," he said.
However, Song said he made the right decision to choose the deal with Spanish Giants Barcelona.
"Suddenly, I was wanted by the biggest club in the world and they wanted to give me a five-year deal. When the best team in the world recognises your talents, it means you must be doing something right," he said.
"I would have stayed but when the Barcelona train comes in for you, that is a once-in-a-lifetime chance and you just can't miss it," he added. (ANI )
