I could challenge the top three - Murray
Andy Murray claims he is close to being able to beat Rafael Nadal, Roger Federer and Novak Djokovic as he continues his comeback.
Murray is on his way back to the top of the world rankings after having hip resurfacing surgery in January.
The 32-year-old had hinted he would retire at the start of 2019 but continues to defy the odds after returning to singles action.
He won his first title since returning in Antwerp last month and the fans' favourite claims his game is coming along nicely.
"I know if I played against the top players tomorrow, there would be a very small chance of me winning that match," the ex-world number one told BBC Sport.
"But I do feel I could win. Seven or eight weeks ago, I wouldn't have felt that was the case.
"It has been an up and down few years but I feel like I'm coming through the other side of it, and excited to see what I can do over the next couple of years."
