Undercover Football Genius

From the author of Ultimate Football Heroes comes the second book in the Johnny Ball series, funny reading for football-mad kids.
Johnny Ball's got a super exciting new job: assistant manager for the Tissbury Tigers! But there's a catch. Johnny's brother, Daniel, is the Tiger's star player and he doesn't want his younger brother cramping his style. Daniel tells Johnny that no one on the team is ever allowed to know who he is. Can Johnny use his football genius to go undercover and lead the Tigers to victory in the League?
