Jannik Sinner continues to take the ATP Tour by storm, having just won a fourth successive Masters 1000 title of 2026.
Sinner added the Madrid Open title to his recent successes in Miami, Indian Wells and Monte Carlo, having also won in Paris last season for five victories in a row.
ATP number one Sinner eased past Alexander Zverev in the Spanish capital, triumphing 6-1, 6-2 in under an hour for his latest title.
And his scintillating form has now caught the eye of Greg Rusedski, who doesn’t believe Sinner can be challenged right now.

Greg Rusedski suggests never-before-seen position for Jannik Sinner
It was posed to the former British number one on Off Court With Greg Rusedski: “Have we seen a player that’s this far ahead of everybody else before?”
He responded: “Not at the moment.
“I think we’ve had some of the youngsters not step up, or the ones we thought would go through, constantly injured, like Jack [Draper].
“He’s been, unfortunately, constantly injured, and he was the guy we thought, okay from a British perspective was going to be knocking on the door.
“And people don’t like playing the lefty. He finally got the shoulder and now the knee’s out. He’s out of the French which is majorly disappointing.
“Ben Shelton, great athlete, but not natural on the red clay. But on any given day with his serve and his tools, you think the backhand’s improving, but you’re like, scratching your head.
“And Zverev is the closest one with his clay court results, and he’s been miles off the last little while. So you’re thinking to yourself, who is the next guy?
“I mean, [Arthur] Fils we were thinking was going to be one of the next guys in the pack, but he’s bound to be tired. He’s done tremendously well.
“Let’s see what happens in Rome. Can anybody get close to him? And from what I’ve seen, doesn’t look like it at the moment, but that’s why we play it, because you never know what can happen.”

Greg Rusedski issues big Carlos Alcaraz Wimbledon concern
While Sinner has been on another level of late, he definitely has been helped by the lack of a real challenger.
Carlos Alcaraz does, of course, pose a major threat, but the Spaniard has been absent from the ATP Tour of late.
Alcaraz watched his brother play in Madrid, but a wrist injury ruled him out of the ATP Masters 1000 tournament on home soil.
He’s also out of the Italian Open and the French Open, with Sinner now turning his immediate focus to the former in Rome.
Speaking of the Italian ahead of his next event, Rusedski said: “He’s got at least four or five days to prepare before his opening match, so there’s plenty of time.
“If you’re not seeded then it becomes a little bit of a drag. So I don’t think it’s going to affect him because he has a big enough gap. And his preparation is second to none.
“And after this week in Rome, if he wins this, five Masters series in a row, week off, then getting ready for the French, there’s going to be a massive amount of pressure.
“And he knows the opportunities. I’ve never seen anybody in my life, the last few years, take their chances and bounce back as well as he did.
“Because after he lost that French Open final, three match points against Alcaraz, we’re thinking okay, Alcaraz has the edge. But he wants to catch Carlos, seven majors.
“Sinner has got a few less and he wants to have all four in his trophy cabinet, because Carlos has it. I have a feeling Sinner is going to have all four by the time we get to the end of the French Open.
“And the thing that I’m concerned about is, I’m not sure Carlos is going to be at Wimbledon this year. Because we’ve seen pictures with the wrist, we saw him watching his younger brother in the stands as well.
“So I think it might take a little bit longer. And Sinner’s making hay right now, he’s winning everything he can at the moment.”
It is a massive blow for the ATP Tour and tennis fans to have Alcaraz out injured, particularly given his thrilling rivalry with Sinner.
They played out a five-set thriller in last year’s French Open final, where the Spaniard prevailed, with the Italian exacting revenge in the Wimbledon final shortly after.
