Paul Marshall has called on Ulster to up their game ahead of Friday's clash with Munster at Ravenhill.
Ulster go into the inter-pro clash unbeaten after two RaboDirect PRO12 wins on the bounce, the latest a 16-13 victory over defending champions The Ospreys on Saturday.
The Irish province, who had posted an opening 18-10 win over Glasgow, were trailing 13-3 with 56 minutes on the clock at the Liberty Stadium but ran in an unanswered 13 points.
Marhsall, who scored the decisive try in the victory, knows his side will have to improve if they are to beat Munster on Friday.
The scrum-half told the club's official website: "Next week will be a really tough encounter as all the inter-pros are.
"I'm assuming they will come up to Belfast with their full contingent of internationals and we will have a couple more back as well.
"We will have to be firing on all cylinders if we are to come away with another win, a performance like the one on Saturday night won't be good enough.
"It's our first inter-pro of the season so it's exciting for the fans, but also the players."
Current Ireland number one scrumhalf Connor Murray is likely to play for Munster but Marshall is focused of getting in the Ulster team ahead of international selection.
"I'm expecting Conor Murray to play on Friday night and he's currently the no1 scrumhalf in Ireland so it will be a big test if I'm selected," he said.
"But the main thing for me is getting more game time with Ulster. Blane McIlroy and Michael Heaney have been playing well so my focus first and foremost is to fight for a place in the Ulster team."
Regarding the win over the Ospreys, Marshall added: "It was a scrappy game and both teams didn't really play well. We didn't threaten enough in attack but I thought we scrambled well in attack.
"I didn't have much to do for the try; I just squeezed over the line when John [Afoa] was brought down just short.
"It was a good team try and it shows what we are capable of producing. We didn't play very well but I thought we showed great character in the second half and the most important thing is that we got the win and it keeps us on track."
