Tennis legend Stefan Edberg believes that Serbian player Novak Djokovic was the reason behind Roger Federer hasn’t won more Grand Slam titles during 2014 and 2015.

Federer hired Edberg as his mentor in 2013 following a massive dip in form. Fortunately,?the pair managed to restore the Swiss star to his former glory. However, he still fell slightly short to Djokovic as the Serbian won Wimbledon for two years in a row.

Djokovic also added the Australian Open and US Open to his list. This left Federer on a four-year drought for a major tournament win.

According to Edberg, if not for Djokovic then Federer would have even more major honours to his name because of his excellent form.

When I joined his team, I felt he could win a Grand Slam,? Edberg said.

?He deserved to win a title in 2014 and 2015, but Novak Djokovic was a bit better.

?As you get older, it obviously becomes tougher. But Roger is absolutely without time.

?What he did in the last years is incredible. Two or three years ago he was a little bit unlucky with majors.?

Federer broke his Grand Slam drought in Australia 2017. Since then, he has won a further two titles.

As Federer’s former coach, Edberg thinks the 37-year-old will continue to challenge at the top of the game because he has lowered his expectation.

?At the 2017 Australian Open he had the necessary luck,? Edberg added.

?The balls that before went out now were falling on lines. His confidence increased and in the end, he won Wimbledon and Australian Open.

?I don’t think that anyone believed he could do it at his age.

?He may have reduced his expectations, so he got relaxed. Roger is unique in many ways: on the court, but also in treating media and fans.?
