McClaren has been linked with West Ham United.
But Munsterman told the Daily Mail: "I've heard nothing. We will see. We've never panicked. My ultimate wish is to have a manager who would stay for 10 or 15 years like at Manchester United and Arsenal.
"I hope Steve will stay for years. But will he? He is very relaxed. If Manchester United comes in and offers him, what can you do?
"I don't have this feeling. He is already working on next season here, he is so eager about the Champions League already.
