"It felt a bit unreal parading the trophy around Eindhoven City on an open coach with my teammates," the 25-year-old Chinese international told Shanghai Daily. "I had seen something like this only on television before," he added.

Sun returned to Shanghai on Sunday, seven days after Eindhoven clinched the Dutch league crown on goal difference. Eindhoven routed Vitesse Arnhem 5-1 in the season's final fixture to deny archrival Ajax Amsterdam by a solitary goal on top of the standings.

PSV had earlier blown a comfortable 11-point lead amid injury woes that saw Sun travel to the Netherlands on loan from Shanghai Shenhua.

The triumph means Sun becomes the first Chinese footballer to win a league title in Europe.

"The past three months have been amazing," said Sun, referring to the Champions League matches - another first for a Chinese.

"I found myself a different player after this experience."

Sun was released on a five-month loan deal in January but the Shenhua player has expressed a desire to continue with the Dutch champions.

"I definitely want to stay on with PSV. I believe I can achieve even more than what Lee Young-Pyo and Park Ji-Sung did for them," Sun said.

The South Koreans were the most prominent Asian players in PSV's service, powering the team to Dutch titles and European successes between 2003 and 2005.

Ronald Koeman's decision to continue as PSV coach should also boost Sun's chances of a permanent transfer.

While his future hangs in balance, his European foray has certainly raised his brand status with advertisers making a beeline for him for commercials. Sun has already drawn the attention of multinational companies, including Britain's GP Batteries, who are keen to use his image to market their products.

"I am excited by the offers not only because of the financial benefits, but also by the impact they would have on people's perception of Chinese soccer," said Sun.

Soccer has suffered in China over the last few years amid match-fixing allegations and on-pitch violence that has kept fans away from domestic fixtures.

"Chinese soccer has been through some rough rides of late and the image of footballers is anything but positive. I hope I can change that."
