The 11 players seem to be sold in the same way as Mystery Figures, in sealed bags. The set number (for all figures, probably) is 72098. Ebay.it sellers are offering them for between 12 and 18 Euro. The collector's case is produced by Blue Ocean (so it may not have a PM set number) and is available for about 10 Euros (no figures). The case has spaces for 16 figures, with the 5 extra spaces suggested for duplicates.
