Nishikori: IPTL rules confusing

Japanese tennis star Kei Nishikori is enjoying playing in the International Premier Tennis League (IPTL) but admits the rules are a bit confusing.

In a chat with India Today television in Kobe, Nishikori said though he was enjoying the IPTL event but was a little bit confused with the rules.

"The team competition is very good; you only have them in Davis Cup. The rules made me little confused but it's real fun on the court," Nishikori said. 

"It's a great event and good opportunity for me to play here in Japan my home country. Moreover, a lot of great players and legends of the game are playing in the league."

The world number eight added that after reaching the US Open final last year his dream was to go one better and win a grand slam title in the future. 

"It was really a good feeling to make into US Open final last year and almost my dream coming true. I hope to make it to a grand slam final soon and move forward from there," Nishikori added.
