That is the verdict of Jonas Bjorkman, the man who coached Murray in 2015, and who has watched the former world no 1 battle his way back from injury.
Murray has so far refused to put a date on a possible singles comeback, after competing in the doubles at Queens Club, Eastbourne and Wimbledon in the last month.
The Scot won the men’s doubles at Queens with Feliciano Lopez, got to the second round at Wimbledon with Pierre-Hugues Herbert, and in the mixed reached the third round with Serena Williams.
Swede Bjorkman, 47, the former world no 4, believes Murray can get back in the mix with Novak Djokovic and co. Bjorkman said: “Absolutely Andy can get back to the top ten level.
“There is no doubt, with the calibre of player he is, if he is healthy, I have no doubt that he is going to be back to challenge the top five.
“Once a champion you are always a champion. He has had a problem with his hip for a long time and that has been throwing him off a bit, but there is no doubt that he can come back to that level and maybe play even better.
“Without pain, without the stress of the pain and not knowing what to do, he’s probably going to have a smile on his face just going out and being more free, when you don’t play with the pain any more.”
Bjorkman added: “It was a smart move to start slowly playing Doubles. It’s a huge difference singles to doubles. It is not so much about fitness, it is more about where to stand and the court coverage.
“Hopefully he will find the right time to play singles. He won’t risk it, for sure.
“Andy is so professional in everything he has done in his career and with such a great team behind him who have been with him for so many years, its no doubt that they will make the right decision when the time is right.”
Earlier this week, Murray’s coach Jamie Delgado said the Scot has set a number of targets he must meet before returning to singles action.
“There are certain physical targets Andy will have to reach before he can play singles. There are no dates set,” Delgado said.
“He will have to have certain strength and speed levels that will enable him to compete in singles. He hasn’t done that yet because of the doubles commitments.
“It is really pleasing to see to him not being in the pain that he was for a long time. He has worked hard to get to this stage.
“He is doing really well. Doubles is much less load on the body, but it is tough because he hasn’t played for so long and it is so quick.
“We are taking every day as it comes. There have been good signs. The pressure is off him. It will just be when he feels good and strong enough.”
Meanwhile, the last Brits left standing in the senior events at Wimbledon saw their hopes shattered last night.
Evan Hoyt and Eden Silva spectacularly blew their chances of making the semi-finals of the Mixed Doubles in bizarre fashion as they crashed 7-5, 7-6 to eighth seeds Ivan Dodig and Latisha Chan.
But the British pair only had themselves to blame.
Welshman Hoyt and Londoner Silva actually led 4-1 in each set and 4-0 in the final set tie break – and still managed to blow it.
The British pair, who at least lasted longer than Murray and Williams in the competition, started each set in blistering fashion last night – but then collapsed.
In the tie break they looked like they had rescued the situation as they led 4-0 and then 5-4 – but the experienced and athletic Dodig and partner Chan held their nerve.
The last three points slipped heartbreakingly away on Court 2 – as Chan’s volley at the net proved the final clincher.
