Squirrels playing soccer

A man comes to a psychiatrist, and the psychiatrist asks him: "What seems to be the problem?"

"Well, doctor, I have these very strange dreams about squirrels playing soccer. At first it wasn't that often, but now it's every night, and besides... I've been thinking about it during the day too, and it really bothers me."

"Okay," said the doctor, "we have good medicines for such things these days. Take the medicine that I'm going to prescribe for you for a month, and then come to see me again. But the problem should be solved by then."

"Doctor, would it be possible to start taking the medicine after a week...?"

"Yes, of course, but why?", asked the doctor.

"Next week is the tournament finale."
