There is something drastically wrong with Rublev. After winning five titles in 2020 - he this year went from bad to worse. Players who never beat him before is beating him with ease this year. It is virtually the same that happened with Thiem - but the latter gave up playing for this year and dropped from number 3 in the rankings to number 9.
Rublev may need advice from experts to get over the present hiatus or he will soon be out of the top 20 in the rankings.
