The Holland international is regarded as key to PSV's chances of challenging for the Eredivisie title next season following the recent departures of Dries Mertens, Erik Pieters and Jeremain Lens.
But the 23-year-old, who is a reported target of Manchester United, told Voetbal International he has also been in talks regarding a switch from the Philips Stadion.
"There are several clubs interested but only when they reach an agreement with PSV do I come into the picture," he said.
"This is not to say that any are in the world's top six.
"There is also interest from Russia, but that is not an option for me. I do not make hasty decisions about my future.
"The opinion of Holland coach Louis van Gaal is also very important with the World Cup in Brazil next year."
Strootman is disappointed Mertens, Pieters and Lens were tempted away from Eindhoven.
"It was very unfortunate that so many players left PSV," he added. "I did not expect Dries Mertens and Pieters would leave the club."
The trio's departure prompted the club's technical director Marcel Brands to say of Strootman last week: "We do not want to lose him.
"He knows himself that he will play another season at PSV."
