"There's healthy respect between the sides, also a bit of niggle," he said.
"They've been a bit of a bogey side for us in the past, although we nailed that at Rodney Parade last season.
"We also face the Dragons in the Heineken Cup so we're going to get used to each other. It's going to be a tasty day, pretty intense."
Glasgow finished in their best Magners League position of fifth last season and are keen to climb higher.
"That's a platform for this year, but we can't count our chickens and make it a one-off, our ambition is to improve," he told BBC Wales' Scrum V rugby programme.
"I think we've got more respect, but if you look at the teams who finished above us in the league - at what they've got on and off the pitch - we are still the underdogs.
"Our players have a lot of belief. There'll be no excuses and we need to play consistently.
"We've made a few new signings and are happy with the squad we've got."
