Australian international goalkeeper Mathew Ryan returned to training on Saturday with Valencia after nearly a month out due to knee surgery.

"The new news of the morning was Australian Mathew Ryan's return to the group," Valencia said in a statement on their website.

The 23-year-old missed Australia's World Cup qualifying victories against Bangladesh and Tajikistan, as well as Valencia's opening Champions League defeat to Zenit St Petersburg.

Ryan could return to action as early as Tuesday when Valencia travel to Lyon in the Champions League.
