And it's the fans who pay for it by having all these kits.
Not really. They are kit combinations versus official kits. Plus nobody “has” to buy them. And interestingly we had 9 combos in 2011/12.
We only had two shirts used in that season with various shorts and socks combos. Fulham have White, Black, Blue and Red shirts, plus shorts and socks.
If you're a parent, you'll pay for it, either in cash or pain.
