return to the upper echelons of German and European football. Borussia Dortmund began the 2001–02 season strongly and eventually won the Bundesliga in 2001–02. That same year, Borussia Dortmund reached the UEFA-Cup final, though the team lost to Dutch club Feyenoord Rotterdam. Around this time, Lehmann developed a reputation for his poor disciplinary record. In a match against SC Freiburg, Lehmann kicked opposing attacker Soumaila Coulibaly after they collided in the penalty area. Lehmann was suspended afterwards. He currently holds the record for most red cards for any Borussia Dortmund player, and the record for most red cards for a goalkeeper in the German Bundesliga. Lehmann's form slipped in the 2002–03 season, along with Borussia Dortmund's. His time at Dortmund was winding down, and after the season concluded, he left Dortmund. He was replaced by Roman Weidenfeller and Guillaume Warmuz, who had just left Arsenal. Arsenal 2003–04 season Lehmann joined Arsenal on 25 July 2003 replacing the recently departed David Seaman. Arsenal's 2003–04 season was historic. The Gunners finished the 2003–04 FA Premier League season unbeaten, becoming the first English club to accomplish the feat in the modern era and only the second to ever have an unbeaten season in English football's top tier, the only other team to accomplish this feat being Preston North End in the 1888–89 season.

He also committed an error that led to the equalising goal in Arsenal's Champions League defeat at home to Chelsea the same season. Despite these mistakes, Lehmann's addition to the Arsenal team had a major effect on Arsenal's ability to finish unbeaten. And Arsenal continued unbeaten until 24 October 2004. At the end of his first season at Arsenal, he had already played 54 times earning himself a Premier League winners medal. 2004–05 season By the middle of the 2004–05 season, Lehmann's inconsistent form lead to Spaniard Manuel Almunia starting in several matches instead. However, Almunia made a series of mistakes during several games, thus allowing Lehmann to regain his position. At the end of that season, as speculation again began to mount that he would be replaced over the summer, Lehmann cemented his position in the
