Pics: Sydney train for derby

Sydney play host to Western Sydney Wanderers at Allianz Stadium on Saturday night for a derby which could define both their seasons...

Wanderers need to win to keep the pressure on Brisbane Roar who seem to be fading as the season goes on, while Sydney need a win to keep their finals hopes alive against a rapidly improving Melbourne Heart and Wellington Phoenix.

Frank Farina took his squad out on the field at Allianz for a training session ahead of the game - with Alessandro del Piero taking centre stage - and Getty Images were on hand to supply the pics. Click on the links to each photo below to see the gallery.
