Newport Gwent Dragons head coach Lyn Jones admits that whilst not an immediate concern, his team's set-piece work must improve.
The Dragons were 22-20 winners over Bath in a pre-season clash away from home last Friday.
However despite the morale-boosting victory, achieved without star players Toby Faletau and Andrew Coombs, Jones admits his evaluation of his squad is still ongoing and that areas such as the maul and scrum will require more time to perfect.
"As a new coach coming in I need to form an opinion on everyone. It was important to see them play," said Jones to the South Wales Argus.
"We've worked on lots with each other over the last couple of months, Bath was an opportunity to do it live. We are quite pleased with the exercise.
"It was glaring that the maul and the scrum areas were a little fragile but that doesn't concern me at the moment. That will take a session or two to put right.
"I will select for Ulster as soon as possible because this team needs time to grow and to gel.
"We have to understand what our first XV is and once we've got that the rest of the squad needs to challenge.
"There are lots of areas to improve on but the biggest thing you can have in the changing room is people who work hard and are honest.
"If we can harness some of that energy (from the defensive attitude against Bath) and put a little bit of tact and guile in then we will be an interesting force."
