3-5 other clubs). Full disclosure: I'm a Palace fan and saw this on some facebook supporter page and did not compile the stats personally. To add some additional uselessness to that fact, I don't know where Arsenal rank on that list, either, and can only confirm City and Liverpool are at the top.
Jenkinson and Mustafi starting together on defense, it aint worth the time.
My guess: Emery went with a weak line up because it was a home match. Wants the best players available on rest for the rest of the away fixtures.
But there are rules: No Jenko and Mustafi requires the other three back to be significantly experienced. Other than that, roll the dice and light a spliff.
