SUMMARY: Round four is probably too early to use the term "must win" when describing games, but Adelaide defender Ben Rutten was right when he said you don't want to be playing catch up late in the season. Both clubs have begun 2013 in awful fashion, winning just one of the their opening three games. Each also suffered embarrassing losses last weekend; the Western Bulldogs to Richmond and the Crows to arch rivals Port Adelaide, so this shapes as a fiercely contested encounter.

WHERE AND WHEN: AAMI Stadium, Sunday April 21, 2.45pm

THE SIX-POINTS
1. The Western Bulldogs have been Adelaide's bogey team of late, with the Bulldogs winning four of the last five encounters between the two clubs.

2. AAMI Stadium is one of the Western Bulldogs' favourite away grounds. They've won eight games at the venue to the home side's 11, including three of the last four.

3. This will be the 37th clash between these sides and, while Crows fans remember consecutive preliminary final victories over the Bulldogs in 1997 and 1998, the 'Doggies hold the overall advantage 20 -16.

4. Scott Thompson was the star for Adelaide in its 2012 win, collecting 34 possessions and three Brownlow votes. The Western Bulldogs' Ryan Griffen was awarded two votes for his 31-disposal effort.

5. These matches usually don’t suit the forwards, with former Western Bulldog Barry Hall the last player to boot at least five goals, in round 5, 2010.

6. Crows coach Brenton Sanderson's connection with his counterparts continues in round four; Sanderson and Bulldogs mentor Brendan McCarthy were both assistants together at Geelong.
