Of course he has a choice. The alternative choice is to play somebody who is fit.
The very reason we've had an injury crisis that has lasted a couple of months is because pep has continuously chosen to throw whoever is available straight back in and push them until they inevitably break again.
We don't even have that many injuries, other teams have more than us, we are down to the bare bones purely because in the summer we settled on a squad whereby we can't afford to lose 2 defenders at once which is madness.
