In 2011–12 season, Júlio César played his 200th Serie A match on 1 October 2011 in the 3–0 home loss to Napoli, saving a penalty kick in the first half. Later on 22 November, Júlio César made his 50th UEFA Champions League appearance in the 1–1 draw against Trabzonspor in the 2011–12 UEFA Champions League Group B matchday 4. This draw was enough for Inter to secure a spot in the round of 16. He reached a century of clean sheets in Serie A on 18 March 2012 by playing in the goalless draw against Atalanta in the matchday 28. This draw meant that Inter have won only one of their last nine league matches. Júlio César's 300th appearance in all competitions for Inter occurred on 6 May in the penultimate week of Serie A against Milan in which Inter won 4–2. He conceded a controversial penalty to Kevin-Prince Boateng and was included in a verbal confrontation with Zlatan Ibrahimović who went on to convert the penalty. He was booked for the penalty which made him miss the final match of the season against Lazio. He concluded his 7th season at Inter by amassing 40 appearances in all competitions as Inter finished sixth in league, with the team just five goals short of equalling their all-time worst concession in a single Serie A campaign. In the Champions League, the team was eliminated in the round of 16 by Marseille on away goal rule and was knocked out of Coppa Italia by Napoli. With some critics believing Júlio César had declined in form since the 2009–10 season, Inter signed Slovenian goalkeeper Samir Handanović from Udinese to take over as first-choice goalkeeper.
