Lehmann had an outstanding 2005–06 season with Arsenal, making his 100th Premier League appearance for the club in their game against West Bromwich Albion on 15 April 2006. He was a key factor in his side's first-ever accession to the Champions League final; during their run Arsenal broke the record for the most consecutive clean sheets in the Champions League with ten, breaking the record of seven that Milan had set just one year before. That run formed the bulk of an 853-minute spell without conceding a goal, overtaking the CL record for an individual goalkeeper set by Edwin van der Sar.
