The Sweden striker has spoken about his troubled past with the Manchester United manager, though he has not ruled out working with him again.
That was the message gleaned from a Sports Illustrated interview with the 33-year-old in which the forward spoke openly about his past dealings with LVG. Paris Saint-Germain signed the striker for £15.7 million, as reported by the BBC.
Asked about his relationship with Van Gaal, Ibrahimovic admitted it was 'not good' citing their previous coming together at Ajax in the Eredivisie.
"He was a director in Ajax and the way he is working is not the way I work," he explained.
Despite his negative memories of life under LVG, though, Ibrahimovic was quick to stress that he would still have no problems working under the Manchester United boss.
"At the end, I think he is professional and I am professional. Whoever I work with, I never had this kind of problems, because at the end I need to do my job, he needs to do his job," he explained.
"And I think a lot of fights would happen but that's something I like."
The news comes amid reports linking the Swede with shock Old Trafford switch.
A report carried by The Manchester Evening News cites several other media outlets suggesting Manchester United could offer the forward a three-year contract.
With PSG since the start of the 2012-13 season, the Sweden international has scored 106 goals in 126 games for the Parisiens, winning a hat-trick of league titles in the process. Last season, Paris Saint-Germain completed a domestic treble of the Ligue 1 title, Coupe de la Ligue and Coupe de France.
