The Welshman hinted he is not ready to put the chequebook away just yet.
"There may be more additions,” he said. “We can't guarantee that but we've done well up to this point.
“We're pleased we done a lot of good work early on. I think that shows in the way the guys are bonding and gelling on the field of play.
“It takes more time when you have players who can't grasp what you're trying to get over and can't understand what's required.
“The guys we've brought in are quality players so it makes it much easier to gel.
“That was an aim of ours to get as many bodies through the door as we could early on. We've been able to do that and we'll continue in the same vein.”
