The full entry list for the Istanbul Cup, to be held from the 18th-24th April, has announced its full entry list for this year's tournament, with Victoria Azarenka and Caroline Wozniacki still set to headline.

Azarenka and Wozniacki had previously been confirmed for the tournament, alongside the likes of Brits Heather Watson and Laura Robson, though 21 of the 32 spots in the tournament have now been filled, with qualifiers and wild cards to be added.

Azarenka And Wozniacki Headline

Former world number ones Azarenka and Wozniacki are by far the biggest stars set to be in action in Istanbul.

Azarenka, who has returned to the top ten this season for the first time in almost two years, is making her first appearance at the tournament and will be the favorite for the title.

Wozniacki missed the tournament last year but won the title in 2014, defeating Roberta Vinci in the final, and the Dane will be looking for a similar performance on her return.

Defending Champion Tsurenko Returns

Lesia Tsurenko is returning to Istanbul to defend the title, and is set to be the fourth seed at the tournament.

The Ukranian won her first and currently only career title at the tournament last year and will be looking for a similar performance this season, following a disappointing start to 2016.

Tsurenko will not be the only Ukranian taking part in Istanbul, with Kateryna Bondarenko also entered into the tournament.
