Ziegler featured in 31 matches in all competitions that season, including 23 in the Premier League. He showed great promise and improvement, and became popular with the fans for his attack-minded play on the left side and good passing ability. One of his most memorable moments from that season came in the home loss to Arsenal. Near the end of the game, he played a delicate chipped pass to Frédéric Kanouté, who scored to make it 4–5. Another memorable moment was in the 1 January 2005 match against Everton, where he scored his first goal en route to a 5–2 Tottenham win. At the time, it was his only goal of his professional career. At the end of the season, he was named the JSM Young Player of The Year, an award given to a young Tottenham player by its junior fan club.
