The Madrid Open 2024 is moving towards the business end as the remaining players are battling to secure the ultimate prize.
In the men’s category, the quarter-final line-up was completed on Tuesday with some interesting matches set to take place over the next couple of days.
One of them will feature Italy’s Jannik Sinner, who is set to face Canada’s Felix Auger Aliassime in the last-eight clash on Thursday.
But the world number two’s involvement in the tournament is now in serious doubt.
Sinner already revealed that he was struggling with a hip problem, before his third round match in the tournament.

Jannik Sinners hits at withdrawing from Madrid Open
And, after his fourth-round triumph against Karen Khachanov, while talking to The Tennis Channel, he stated that he is still not 100 per cent.
Sinner also hinted that he could withdraw from the event, with an intent to be fit enough to compete in big events such as the French Open and the Wimbledon, which are now coming closer on the horizon.
“The body felt better than yesterday, still not 100 per cent,” said Sinner. “But you know tomorrow we have one day off. Let’s see what I can do.
“Obviously, I don’t want to risk for the big tournaments like Roland Garros, Wimbledon you know. Also, Rome for me is a big tournament. So let’s see what’s coming.
“Today I felt that I was able to compete with what I showed. In my mind its also normal I played many matches throughout the season until now, so you know its normal to have you know some little pains but in other way, I am happy to be here, happy to be in a position. It’s a good problem to have I always say and so let’s see what’s coming now in the next round.”
Jannik Sinner must make the most of his red-hot form
Sinner is going through arguably the best phase of his professional career, especially since the Davis Cup, as he has been unstoppable on the tennis court in the last six months.
The world number two is having a fabulous 2024 season. He has already won his maiden Grand Slam after beating Russia’s Daniil Medvedev in a five-set thrilling final at the Australian Open, and he is also triumphed on Rotterdam and Miami.
Those performances have put him in the spotlight alongside Spain’s Carlos Alcaraz and Serbia’s Novak Djokovic ahead of the busy Grand Slam season.
Therefore, Sinner must make the most of his red-hot form and ensure that he will participate in all the major events with full fitness, even if that comes at the cost of missing out on some ATP events.
