Zeljko Kalac is an Australian goalkeeper of Croatian descent who made his international debut in 1992. Since then he has played in over 50 international games, his most celebrated stint being with AC Milan. Known as the Spider on account of his two meter plus frame and flailing arms, Kalac started his career with Sydney United. He later moved to Leicester in Europe but it was not an eventful sojourn.

A call to Roda JC, a little later, gave Kalac the push he needed. The Dutch side reached the last 16 of the UEFA Cup in 2002, and Kalac moved to Serie A with Perugia. Luck smiled on Kalac when Perugia's fortunes dipped, and Kalac found himself as the back up keeper to the celebrated Dida in the AC Milan goal.

An ankle injury to Dida brought Kalac into his own. Besides Champions League, Kalac got a chance to play in Coppa Italia. The preparations for World Cup 2006 saw Kalac being summoned to do national duty, as deputy to Mark Schwarzer.

Kalac may not be number one goalkeeper of the Socceroos but he certainly is one of the most experienced goalkeepers in the game. He is also the most reliable, and can be expected to keep most forwards at bay.
