The Bulldogs were considered a top four hope just a month ago before suffering four straight defeats, culminating in Sunday’s 28-12 sudden death semi-final loss to Penrith.

Hasler said he would be reviewing his side's end of season capitulation.

“It was very disappointing, we were inconsistent all year,” Hasler said.

“We will have the whole off season to think about it.”

Hasler was once largely considered the best coach in the game, leading Manly to the 2008 and 2011 premierships.

Success followed at Belmore with grand final appearances in 2012 and 2014, both of which were lost to Melbourne and South Sydney respectively.

But is seems the Bulldogs' style of having hard-running big ball playing forwards is no longer as effective.

Retiring winger Sam Perrett backed Hasler to have a plan to re-energise the Bulldogs as they continue their search for their first premiership since 2004.  

“Des always has the wheels spinning, “he said.

“I’m sure he will be spending a lot of time in the off season on how we can do things differently and better next year.

“Working out how we can do better, because there are a lot of shattered boys here.”
