Defence will be the buzzword at Bulldogs' training this week, given the Tigers' ability to put points on the board in a hurry.
"Yeah, and that can be off tackle two, three, four or the last,'' Hasler said.
"You've got to defend well because they ask you so many questions at the line.
"Both (Benji) Marshall and (Robbie) Farah, that's their trademark.''
Someone who knows all about the danger those two players present is Bulldogs' back-rower Dene Halatau, who won a premiership alongside the duo in 2005.
"They've got two of the best attackers in the game, I think, in Robbie and Benji,'' Halatau said.
"They test you across the park. We can't have any player lapsing in defence or they'll catch us out.
"Our focus should be on ourselves and making sure we've got our defence right.''
