Zeljko KALAC

On 21 November 2006, Kalac made his second UEFA Champions League appearance for Milan as he came off the bench in the final 15 minutes of the group match against AEK Athens. Dida tore knee ligaments and was predicted to be out for two to three months, which finally gave Kalac a chance to make more competitive appearances for Milan. Kalac's first full game in the 2006-07 season was on 25 November 2006 in Milan's 1-0 win over Messina in the Serie A.

On 14 January 2007 Kalac suffered an injury against Reggina and was replaced by a recovering Dida for the following match against Lazio. These goalkeeper injury concerns prompted manager Carlo Ancelotti to sign Messina goalkeeper Marco Storari, who became the third goalkeeper in the Milan first team with veteran Valerio Fiori being the fourth. Storari replaced Dida and Kalac in Milan's Serie A matches against Livorno and A.C. Siena in mid-February, when both were out with injuries. Despite this extra competition, Kalac recovered from injury in time to play for Milan in the first leg of the UEFA Champions League round of 16 against Celtic on 20 February. In the next Serie A match against Sampdoria five days later, Dida was nevertheless able to make his comeback after being out for nearly one month and subsequently remained in goal until suffering a shoulder injury in mid-April, which enabled Kalac to make further two Serie A appearances before Dida returned in goal for the first leg of the UEFA Champions League semifinals against Manchester United on 24 April. Kalac finished his second season at Milan having made 10 appearances in the Serie A and another 3 in the Champions League.

In March 2007, Kalac signed a contract extension with Milan, keeping him at the San Siro until at least 2009. In the 2007-08 season, he made appearances in the Champions League again after Dida was suspended for simulation in a match against Celtic, helping Milan through to the knockout phase. Kalac made a number of appearances in the Serie A, after Dida suffered a combination of injuries and poor form midway through the season. Kalac notably kept a clean sheet away to Fiorentina on 3 February 2008 as he snuffed out a Fiorentina attack moments before the final whistle, a save that earned praise from media and coach Carlo Ancelotti.[10] Later in the month he collected another clean sheet at the Emirates Stadium against Arsenal in a 0-0 draw during the first leg of the UEFA Champions League round of sixteen, producing several good saves in the second half and being named Man of the Match by UEFA. In the second leg of the tie, he conceded two late goals as Milan were eliminated by Arsenal after a 2-0 loss at the San Siro.

The combination of Christian Abbiati's return from his loan spell at Atlético Madrid and a poor performance in Milan's 5-0 Russian Railways Cup thrashing at the hands of Chelsea F.C. on 4 August 2008[12] spelled the end of Kalac's brief first-team run. He was consequently demoted to third-choice behind Abbiati and Dida, and did not play for Milan again until appearing in the second half of a friendly against Hannover 96 on 29 January 2009, and one Serie A appearance against Juventus as an injury replacement on 10 May.
Kalac was released by Milan on 11 August, following an agreement reached with the club.
