The British tennis ace has struggled for form and fitness since winning the US Open in 2021 and Robson thinks she can compete at the highest level provided she remains healthy and consistent.
The former player told Sky Sports: "The game style has been a bit more aggressive over the last couple of months, which is great, but I think also it's a learning curve.
"When you look at her results when she has played well and consistently – she can beat almost anyone. She's a great player with such an attacking game style but you just need to be able to do that day in, day out."
Raducanu has climbed to 55th in the world rankings after starting the year outside of the top 200 but Robson believes that there is plenty of potential for her to climb even higher.
The former junior Wimbledon champion said: "When you think about the months that she's missed, to climb to the ranking she is now, it's actually impressive. In that respect, she's done really well. I think everyone, including her, would like to see it happen more often.
"It's all about figuring out what works for you and maybe she just got unlucky over the last few weeks because that would have been a run of four or five events in a row, which would have been great, but then you pick up one little injury or niggle and you have got to start again all the time.
"When you have the opportunity to play, she's now realised that that's the way forward and if you can play back-to-back weeks then go for it."
