At the start of 2003–04, Solskjær found himself as United's first-choice right winger. However, a knee injury suffered against Panathinaikos on 16 September 2003 put Solskjær out of action until February 2004. Solskjær returned from the injury for the season run-in and was man of the match in the FA Cup semi-final victory over Arsenal. He also played in the 2004 FA Cup Final, which the club won. Solskjær was forced to undergo intensive knee surgery in August 2004 and had to miss the 2004–05 season entirely. While he eventually recovered his fitness, it was difficult for the 32-year-old to carve his niche again among the heavy-weight attack of Manchester United.
