The Gunners 5-1 Champions League victory over Inter Milan ended Blues record that stretched back more than forty years.
Blues beat the Italians 2-1 at the San Siro in the semi-final of the Inter City Fairs Cup (the UEFA Cup as it is now known) in 1961 and went on to reach the final of the competition only to be beaten 4-2 by Roma.
However, the record of Blues being the only English club ever to beat Inter at their own stadium has now ended with The Gunners demolition of the Italians on Tuesday night.
