Corey Norman is predicting halves partner Mitchell Moses to have his best game yet in blue and gold against former side Wests Tigers on Sunday as Parramatta begin to believe they can mount a serious run in September.

Seventh-placed Parramatta have their eye on a first semi-finals campaign since 2009 but, according to Norman, they also have the capacity to challenge for a long-awaited premiership.

If they are to secure a finals spot and go on with it, it is very likely they will need halves pairing Norman and Moses to be prominent.

Moses kicked the winning field goal in the Eels' last start against Melbourne before a weekend bye but it is Sunday's clash with the Tigers at ANZ Stadium that has loomed large on the calendar for him since he was released from his contract at Concord by Ivan Cleary in May.
