Zlatan Ibrahimovic has pledged his future to Paris St-Germain after claiming a league trophy with his sixth different club at the weekend. The 1-0 win against Lyon means the 31-year-old has now won eight titles at Ajax, Inter Milan, Barcelona, AC Milan and now Paris St-Germain. Two further triumphs with Juventus in 2005 and 2006 were later stripped as punishment for a match-fixing scandal. Speaking on Sunday, the Swede vowed to add to that number with PSG next year. "I am very pleased," he told French publication L'Equipe. "I have had a perfect start here in Paris. "I could not have dreamed of anything better. I am now going to do my best to defend the title. "I am under contract for another two years. I am a professional and I respect contracts." Ibrahimovic has won the title in four different countries, and from 2003-04 to 2010-11 the side he played for finished top of the standings. Ibrahimovic arrived in the French capital last summer after AC Milan sold himself and Brazil international centre-back Thiago Silva to the ambitious Qatari-financed club. In a typically productive debut campaign, he has scored 27 goals in 32 Ligue 1 games. Ibrahimovic was especially pleased to have played a key role as his expensively assembled team took their first league crown since 1994. "When it is the first time, it is always fantastic," he added. "If PSG had won last year, it would be different. "As it is, the club has been waiting for this for 19 years. I am here at the start of this wonderful story. It could not be better." In an eventful evening for Ibrahimovic, he was further involved in a row with sporting director Leonardo as he was asked to go through an anti-doping test just after the game. "The team was celebrating," said Ibrahimovic, "and I was there stuck like an idiot for 20 minutes. "Then I asked to go and nobody came to pick me up. For me it's stupid situation because I wanted to celebrate with my team."
