Novak Djokovic has had to pull out of doubles action at the Monte Carlo Masters, due to an injury sustained by his partner, as reported by the Daily Express.

Novak’s doubles partner Filip Krajinovic has an on-going problem with his left foot which continues to disrupt his progress in competitions, as it also saw him miss the Australian Open back in January.

It is fair to say that it hasn’t been the best start to 2018 so far for Djokovic either. The Serb hasn’t won a single tournament so far and has been blighted by injury problems himself.

The twelve time grand slam winner failed to make it past the last sixteen at the Aussie Open, losing out to 21-year-old South Korean, Chung Hyeon.

Andre Agassi, who was previously Novak’s coach, has now now completely left the team, making it somewhat of a fresh start.

Djokovic will be hoping he can now focus entirely on his singles matches, in order to return to his 2016 form.

The 30-year-old’s quest to return to winning ways starts later today with his match against Dusan Lajovic.
