Despite being compared to Thierry Henry and early-season goals against Norwich City and Bolton Wanderers, the 2004–05 campaign proved frustrating for Bellion as he found himself increasingly frozen out of the first-team squad. His season was curtailed in early May, when he suffered a fractured fibula against Charlton Athletic Reserves. During 2004–05, Bellion scored his first Champions League goal (not including qualifiers) in a 6–2 win over Fenerbahçe and was involved in the squad for the FA Community Shield in a 3–1 loss against Arsenal.
