NAITASIRI Northern Bulls are hoping to maintain its unbeaten run in the B-division rugby competition.
After making their debut last year, the Handy Finance-sponsored side started this season's campaign on a high by thumping Rewa 33-0 last Tuesday.
The side has not lost a single game since last year but failed to make the semi-finals on a points difference.
The Bulls beat Kadavu and drew with Rewa last season and have a win in the bag already earlier this week.
Now, the Manasa Radrotini-coached side faces an uphill battle against Serua.
Radrotini said the second game would be a challenge to maintain their standing in the competition.
"We need to polish up on the execution of the basics of the game perfectly," he said.
"Against Rewa, the boys played well and it was near perfect but I still believe we need to improve our game."
Serua also started its B-division campaign on a winning note with a 21-3 victory over Kadavu. A win for either team could nudge them closer to qualifying for the semi-finals.
Radrotini said their line-outs and scrums were areas they needed to work on ahead of their game against Serua which he added would not be an easy side to topple.
Serua coach Paula Nasara said playing against the Bulls would be interesting.
"The Bulls won their first game so it is going to be a tough battle," he said.
"We just need to play to our own game-plan and make use of our possessions to score points."
The game kicks off at 12.30pm at Ratu Cakobau Park. In the second game, at 3pm, Rewa plays Kadavu.
