Problem:Passage: Brandon signed a two-year contract with Division Two side Chesterfield, and made his debut against Queens Park Rangers on the first day of the 200203 season. Chesterfield lost the game at Loftus Road 31. Brandon's first goal for Chesterfield came a week later when he scored a 12-yard overhead kick to give them a late 21 victory over Port Vale. He scored again just ten days later as Chesterfield defeated Northampton Town 40. His third goal was another volley during a 10 victory over Stockport County. However, he was substituted at half-time, and he did not play for another two weeks because of suspension, until he scored again in a League Cup game against West Ham United live on television, which Chesterfield lost on penalties. He scored in both the first and second rounds of the Football League Trophy, but Chesterfield were defeated on penalties by Port Vale in the second round. He finished the season with ten goals but also 11yellowcards. However, he played only one game during the final month, with his last game coming on 21 April 2003, when Chesterfield finished with just nine players because of serious injuries to Brandon and striker Caleb Folan. Chesterfield picked up four points in their final two games without Brandon, and avoided relegation by just one position, finishing two points above Cheltenham Town. Brandon's ten goals meant he finished as Chesterfield's top goalscorer and also helped Brandon win three awards at the club's end of season awards, as well as reported interest from nearby Nottingham Forest, who had missed out on promotion to the Premier League.

season?
Solution:
Answer: John Gregory
