Nearly four months after they played a pulsating final at the Olympic games in Rio, Carolina Marin and PV Sindhu will resume their rivalry at the Superseries Finals in Dubai starting on Wednesday. The pair have been drawn in the same group for the season ending tournament, featuring the top eight ranked players in the Superseries rankings, and their encounter will climax the group stage of the competition on Friday.The Superseries finals is played in the same format as the ATP & WTA tours year ending events with the players drawn in two groups of four each. At the end of the round robin stage, where they play each other once, the top two players qualify for the semifinals.Although Marin leads Sindhu 5-2 in their head-to-head encounters, she has struggled to maintain her form since the Olympics.

Marin hasnt reached the final of any of the three tournaments she has competed in since clinching the Olympic Gold. She has in fact lost her top spot in the rankings to Taiwans Tai Tzu Ying, who beat her in a three game semifinal at the Hong Kong Open recently.Sindhu, on the other hand, has been in eye catching form recently. After exiting early from her first two tournaments after the Olympics in Denmark and France, Sindhu produced a sparkling run in China, where she won her first Superseries title and then reached the final in Hongo Kong, where she was beaten by Ying.Having missed a few Superseries events at the start of the year with injury, Sindhu wasnt expecting to even make the cut for Dubai, but these two sizzling performances helped her accumulate enough points to sneak in late. Speaking recently to ESPN, her coach Pullela Gopichand had said he was pleased to see Sindhus evolution as a player, especially the additions she has made to her arsenal of strokes.?While the clash against Marin will be eagerly anticipated, Sindhu will be keen to make a strong start at her first appearance at this elite event. On Wednesday, she plays Japans Akane Yamaguchi to get her campaign going. Sindhu leads the head to head against Yamaguchi 2-1 and has won both their previous clashes, including on
