In the first league game of the 2007–08 season, Lehmann made a serious error after just 52 seconds, allowing David Healy to score for Fulham. However, Lehmann's blushes were spared late in the game as Arsenal won 2–1. In his second league match against Blackburn Rovers he fumbled a David Dunn shot to allow Blackburn to equalise, in a game that finished 1–1. On 24 August, the BBC reported that he returned to Germany to treat an Achilles tendon injury which he picked up during international duty against England, meaning Manuel Almunia took his place for Arsenal's third match.
