Ulster's Chris Henry praises the impact made by fellow flanker Marcell Coetzee since the South African made his debut in February following his recovery from injury.
"Marcell is a great personality with bucketloads of positivity and energy," enthused Henry as the Irish province prepare to face Zebre in a rearranged Pro12 game on Saturday.
"The key is getting that fourth spot and then when you get into the semis you have a chance.
"It feels like we are a bit under the radar at the moment and that suits us perfectly. Hopefully having just the Pro12 to focus on can be used to our advantage," he added.
