Neil Jenkins is confident Wales will hit greater heights in the Six Nations as they prepare to face grand-slam contenders England.
Wales visit Twickenham on March 12 with both teams unbeaten in the tournament, although an opening-weekend draw with Ireland sees Warren Gatland's side trail England by one point.
Victories over Scotland and France have lifted Welsh morale, and Jenkins has warned that there is more to come.
"I don't see why not," he told a media conference when asked if Wales can improve further. "We're always trying to progress and get better.
"We're looking to improve every time we come together. We're a side that gets better the longer we spend together.
"If we can win at Twickenham we've got a very good chance of winning the title. If we want to match the southern hemisphere sides we have to keep getting better.
"I'm not too sure we'd have created the amount of chances we have this year, last year. We've just got to be way more clinical. Whether it be decision making, accuracy of the pass, there are a lot of things we can work on and keep improving.
"The boys have played a lot of rugby and I’ve certainly seen an improvement in the boys. I certainly think we’re getting better as the tournament progresses.
"We've got to go up a couple more gears at Twickenham."
Jenkins, who is unsure whether Rhys Webb and Luke Charteris will be available, hopes Wales' recent record at Twickenham - where they have won two of the last three matches - can end England's grand-slam hopes.
He added: "I've been there [Twickenham] on many occasions and had a few hammerings. But since Gats [Warren Gatland] has taken over we've won there on a couple of occasions, they've been massive victories for ourselves.
"It's a stadium that we've won games in, we've beaten very good England sides. It's a tough game and a tough place to go, but there's a lot more confidence playing in the team today than what we had in my day."
