Master League/PES shop secret players

I was wondering where to put this but I wasn't sure where (please move if it isn't in the right place). The players you buy in the PES 5 shop can't be used and it's frustrating as hell. I was wondering how to use them, Match mode particurlarly, but anything would be fine.
