foul, but when a defender has a tiny touh with a striker and he goes down it's a pen?

The quote is the commentator's expression and it was approving as in "he only budnled him off the ball."

Please explain in simple terms that don't require me to understand this sport. Don't be silly. Just something like:

You can only manhandle defenders, not forwards
or
The ref cocked up.

or whatever.
