Australian Open 2012: Fourth round

Spaniard Nicolas Almagro returns to the Australian Open this January hoping to break the habit that has seen him fall at the fourth round in each of the last three competitions. The right-hander will need to curb the temper which has blighted his game in the past, and transfer his clay court successes on to the hard ones in Melbourne, if he wants a fair crack at reaching the tournament's latter stages.
