In Tennis, success isn’t just determined on the court, thanks to endorsement deals and appearances, players can make a lot more money through the year away from the tournament.

We are not talking about a few quid her either, endorsements with international brands like Nike and Rolex are sort after.

Below are the top 10 players who have received the most earnings on and off the court in 2015.

Despite a poor summer where she was knocked out in the first round of the US Open, Ivanovic had a very good 2015 as she finished the year as No.5 in the world.

Alongside her $1.8million in tournament winnings, thanks to some modelling and endorsement deals with Shiseido and Dubai Duty Free she raked in an extra $6million.

9. Stan Wawrinka: $11.1 Million Total Earnings

Thanks to his performances on the court in the last two seasons, Wawrinka has been able to sell his interesting fashion sense through Yonex.

In 2015 he has been rewarded for his achievements in the Grand Slams and the ATP Tour, taking home $3million in prize money.

Finishing the year as World Number 4 also comes with the bonus of an appearance at the ATP World Tour Finals this month.
