Marc Ingla was during this time Barcelona's marketing director and confirmed the rumours in an interview with Telefoot.
"Why didn't Zlatan have luck at Barca? The Swede is a beast, he 's a maschine but he had to work next to another maschine," he said laughing.
"He was too demanding and Messi needed more space. There were some tensions I think," he said.
"I think he will sign a new deal. they are negotiating. He is very happy at Barca and I think we will finish his career there," he predicted.
