The Bombers and Cats will meet at Leitchville in what's a keenly-anticipated clash between the HDFL's only two undefeated teams.

The Bombers have shown early they have the capacity to be a force in the HDFL this season with four victories by an average of 75 points.

But have they improved enough to serve it up to the three-time defending premier Cats?

Since Leitchville-Gunbower joined the HDFL in 2010, the Cats have made a habit of beating up on the Bombers, winning their eight encounters by margins of 151, 111, 149, 63, 101, 81, 56 and 58 points.

"Lockington is still a very good side and the side to beat again, as they have been for the past three years," Bombers coach Marty Shadbolt said on Friday.

"We know it's not going to be an easy game, but we believe if we bring our best game we can mix it with a side like Lockington."

The starting point for Shadbolt on Saturday is just that - the start.

"We need to get ourselves in the game nice and early," Shadbolt said.

"And tomorrow is probably a mental thing as much as ability. Over the past few years Lockington has given us a fair touch-up, so hopefully, our blokes realise their potential, we play our type of footy and the boys understand we can mix it with the best."

If the Bombers can be in the game early, they have shown they get better the longer matches have worn on this season.

The Bombers have outscored their opposition by an average of 52 points in second halves in their four games.

"We're a lot stronger and a more even side around the park this year," Shadbolt said.

"We know Lockington still has a lot of top players in their team that we will need to keep an eye on, but we have to make sure we don't go too defensive. We think we can give them a few headaches trying to match-up on a few of our blokes as well."

So far so good for Leitchville-Gunbower, but by 5pm on Saturday both Bombers and HDFL rivals will have a much better understanding of just what the club that only two years ago won one game is capable of this season.
