That’s the view of Chicago radio host Mark Carman, who still has faith the 30-year-old can mix it with the best.
Djokovic was knocked out of the Australian Open by South Korean Chung Hyeon in the fourth round and underwent elbow surgery soon after.
Since coming back from that operation, Djokovic has lost three games in a row including being knocked out of the Miami Open by Benoit Paire.
It’s the first time the Serb has lost three in a row since 2007 and came despite winning his previous 16 matches in Miami.
It casts serious doubts over Djokovic’s future with the 12-time Grand Slam winner admitting he may have to re-think whether he will appear at next month’s Monte Carlo Masters.
Last year was the first time since 2009 that Djokovic failed to reach a final of a Grand Slam, quarter-finals at the French Open and Wimbledon the best he could do.
But WGN Radio host Mark Carman believes the former World No 1 can bounce back.
“Refuse to rule him out. I would bet on him to win another major at least. Only 30. Supposedly pain free now,” Carman tweeted.
There’s no doubting that Djokovic is a legend of the game, being only the eighth man to have won the career Grand Slam.
He has won 68 career titles – an amount that would have surely been more had he not spent his career alongside Roger Federer and Rafael Nadal.
Indeed, Federer is 36 but still won the Australian Open this year.
