The 2012/13 had a total of 24 Manchester United SoccerStarz collector cards released. The initial 8 which formed part of Series 1 had the text information box at the bottom of the collector card. The other 16 were released later in the collection and no longer had that text box on the card.
SoccerStarz then released a Manchester United 20th League Title winners celebration box set, this featured a set of 24 figures and 24 collector cards. The initial 8 were updated to match the new style collector card and make the set generic. The Mike Phelan collector card is exclusive to this box set, the figure as released in the blind bag but without collector card, so to obtain the Mike Phelan collector card you needed to purchase the box set. Alexander Buttner was not included in the box set, his collector card can only be acquired by buy the single blister pack.
The 2013/14 saw a further 9 Manchester United SoccerStarz Collector Cards added to the collection. As the Manchester United kit was not repainted there were no need to update the collector cards either, so it was the 4 away figures and 5 new sculpts that had new cards released.
