"I'm afraid Thiem's best days are behind him. He hasn't shown enough progress in the last 8 months. We have seen how the Top 3 bounded back from injuries, especially Rafa and Roger winning Slams and Masters 1000 right away," they wrote.Here are a few more reactions to Jez Green's comments:Ghadi@ghadanrahl@WeAreTennis @tennishead Thiem is a good player but I don't think he could beat them at their best...

Lost 2 FO finals to Nadal and 1 AO final to Novak. He got Djokovic in the FO semi in 2019, but went on to lose to Nadal.

"He did it not just once but four or five times to come back from a long injury time of six months or even more. And the form was always amazing. So it’s a great inspiration.”
