Newcastle United boss Alan Pardew is angry being blocked from making an emergency goalkeeper signing.
Injuries to Tim Krul and Rob Elliot mean 21-year-old Jak Alnwick will make his first ever senior start at Arsenal tonight, with 17-year-old Freddie Woodman on the bench.
Pardew told the Evening Chronicle: "We have two fit professionals and until you're down to one you can't call that emergency loan on. Freddie Woodman is one, even though he's 17.
"Karl Darlow can't be called back so that rule (if he's counted as one) is wrong. If every other club can have an emergency loan and we can't purely because we've got a player whose out on loan for a year doesn't make sense. I think that is going to be looked at."
