I don't think very many people would consider soccer to be a contact sport.
Anyways, it is possible you could have some scar tissue in your knees that causes the pain. If it is affecting your lifestyle or workout regimen I would suggest seeing an orthopedist or sports medicine doctor. I get a similar pain during squats, but I have torn (and had reconstructed) my ACL, so I know the source and causes.
