Do what? :D
Sub a Substitute goalkeeper for an outfield player. As Caleyjag pointed out (and I missed), the announcer had Rooney as the sub GK, and this seems to be where the problem arose.
Life is tougher without names on shirts. Which reminds of the wee man (about 10yo) I saw at East End Park, and today, with "3 Djebi-Zadi" on the back of his 09/10 away shirt - how'd he do that then?
By going to a shop and asking for it on the back!
Pretty obvious Allison didnt come on outfield but you could do that if you wanted. If you really wanted you could sub Rooney for Esson and put rooney in goal and put allison on upfront for foran.
a: So which shop would that be then?
b: No, you can only replace a keeper with an outfield player if either the keeper has been sent off, or the keeper has been taken off injured. You can only sub the sub keeper for an outfield player if the outfield player is playing in goal for one of the aforementioned reasons (or immediately following the sending off/injury for any outfielder).
I dont know what specific shop this guy went to, but i've had names numbers put on my shirt before in the Market and there must be other places where you can get it done as well.
For the rule, where on earth are you getting that!? You can sub anyone for anyone you want. There have been instances where sub keeper has been brought on outfield. And if you really wanted you could sub a striker into goal but it just never happens. Everyone is registered as a player not in specific positions so everyone is free to play in what ever position the manager wants, at any time.
