The brace took Ball’s tally to six in those five games and the free-scoring Blues have now clocked up two fours and a three making them the section’s top scorers. Poole has three to his credit and is forming a useful partnership with Ball who was on the bench for the senior side in the recent Carling Cup win over Fulham.
The reserves’ only blip was at home to Liverpool last week and their next outing will see them entertain Burnley on October 20.
