Julian started out in his homeland with Club Atletico Platense in 2000, but the following year moved to Scottish club Dundee, where he soon became a cult hero under boss Ivan Bonetti.
He picked up a Scottish Cup runners-up medal in 2003, follow a narrow 1-0 defeat against Rangers, before heading south to Premier League new boys Crystal Palace, for £500,000 the following year.
Julian made his top-flight debut against Norwich City that August but was utilised as a back-up to Gabor Kiraly before taking the shirt on a permanent basis in 2007.
The Argentine then flourished, winning four consecutive Player of the Year titles – the first player to achieve the feat in the club’s history.
He was undoubtedly one of the star keepers in the Premier League in 2013-14 and his form was a major reason why the Eagles maintained their top-flight status under Tony Pulis.
Speroni had another consistent Premier League campaign in 2014/15 and ended the campaign with a successful testimonial game against former club Dundee.
He equalled the club's goalkeeper appearance record when he made his 388th appearance against Southampton towards the end of the 2015/16 season and has now made over 500 career appearances.
Julian is a former Argentina U21 international.
