The Israeli tournament is low key but Djokovic has achieved his aim of playing matches and is yet to drop a set, seeing off Russian Roman Safiullin 6-1 7-6 (7-3) in their semi-final on Saturday.

It's always a fantastic challenge to play Novak," said Cilic. "No matter the tournament, he is always an unbelievable competitor and always gives his incredible best.
"We first played in (2008) and we've known each other since we were 14 years old so it's going to be another great match, and great for both of us to get in shape for the rest of the season."
At the Sofia Open, top seed Jannik Sinner's bid to win the title for a third year in a row ended when he retired one game from defeat in his semi-final against young Dane Holger Rune.

In the final he will take on first-time ATP Tour finalist Marc-Andrea Huesler from Switzerland, who defeated Italian Lorenzo Musetti.
