I found a brief clip of this Soccer scene. There are also boys in white Adidas shorts (red stripes) and light blue shorts (dark blue stripes, no inner briefs ?) and medium blue short (white stripes, inner briefs).
Most shorts are rather tight. I prefer the dark blue ones (no inner briefs).
The series is probably not worth buying for just this brief scene, but there are also other scenes of interets including Lederhosen, pajamas, underwear and the like.
