10 Most Unpredictable Goalkeepers Of All Time

Some of the goalkeepers are list are considered eccentric for their off-field antics, while others made the cut for their exploits on the pitch. Mark Bosnich, however, has had his fair share of unpredictable moments on both.

The Austrailian began his professional career at Manchester United but failed to earn a place in the first team. In the years that followed, duality became a hallmark of Bosnich's career. A spell at Aston Villa saw the Aussie play the best football of his career while also being fined £1000 by the FA for doing a Nazi salute in a game against Tottenham.

Returning to United in 1999 with the unenviable task of filling a Peter Schmeichel-sized gap between the sticks, Bosnich again produced something of a mixed bag. He kept a clean sheet in United's 1999 International Cup win, but fell out of favour after the signing of Fabien Barthez. His second spell under Alex Ferguson was ultimately short-lived, with the legendary manager describing him as "a terrible professional."

Matters off the pitch would only get worse for the Australian international. After signing for Chelsea on a free, Bosnich would make just five appearances for the club before developing an addiction to, and eventually failing a drugs test for, cocaine - effectively ending his career in British football.

The story has a happy ending, however, as Bosnich returned to football after a five-year hiatus, playing for Central Coast Mariners and Syndey FC in his native country.
