Head coach Richie Murphy says Ulster must play to their strengths to overcome Exeter Chiefs in Friday's Investec Champions Cup encounter at Kingspan Stadium (20:00 GMT).

While both teams are winless in the Investec Champions Cup this season, a victory for either side would keep alive their slim chances of reaching the knockout stages.

"I think it's going to be a really tough game, obviously both teams haven't won in Europe yet so there's a prize in relation to that," Murphy told BBC Sport NI.

"We felt the second half of the Leicester game got away from us and we probably went into our shell a little bit.

"This week is all about going back to what we do well and trying to get the ball on the pitch, trying to play to the space."

Ulster have been forced to deal with a mounting injury list this season, especially in the backline with Rob Lyttle named on the bench for Friday's game after being brought in on a short-term deal to help cover the club's back-three shortages.

"There's a couple of boys coming back in now, we'll have that experience of Mikey Lowry whose being around for a long time now. Moore coming back in at full-back gives us something as well," added Murphy.

"Rob coming back into the front row settles that down a little bit as well."

Despite losing five of their past six games, Murphy believes Ulster are getting back on track.

"We're not happy with the results over the last couple of weeks," he admitted.

"But we feel like we're moving in the right direction so we've just got to keep building."
