I have been told by a friend of mine who works for the company that organizes the events for the A-League (she was recently part of the team that organized the Asian Cup draw) has it on good authority that Jason Derulo (insert auto-tune whining) will be performing at the 2014 A-League grand final.

The only reason I'm putting it in the rumour mill is because I don't have a physical source for it. She's reputable, though.

As for songs, or as to whether it's going to be pre-game, or half-time, I'm not sure as of yet.
