Western Bulldogs star Marcus Bontempelli says he’s struggling to identify the reasons for the sides slump in form in 2017.

The 2016 AFL premiers now sit in 9th place on the ladder, with just six wins from 12 rounds played so far.

Bontempelli (pictured) says with the teams expectations not being met on and off the field, the side will need to dig deep on Saturday night when they take on North at Docklands.
