Radwanska lost to world number one Serena Williams of the USA in the 2012 Wimbledon final
6-1, 5-7, 6-2. Currently ranked number six, the Pole achieved a career high ranking of two in July 2012 following the London final round.
However this year at Wimbledon, Radwanska suffered an early fourth round exit as she crashed out to the 22nd seeded Ekaterina Makarova of Russia 6-3, 6-0.
Navratilova follows in the footsteps of Boris Becker of Germany, Stefan Edberg of Sweden, Amelie Mauresmo of France and Ivan Lendl of the Czech Republic, who are all former Wimbledon champions that after retirement from the professional tour, have chosen to coach current professional tennis players.
"Her achievements speak for themselves and I hope that I can learn from all her experience," Radwanska said.
"She is my tennis idol. We are originally from a similar part of the world, so we share an understanding about tennis and life, which I'm sure will translate into a successful relationship."
The 25 year old, voted the WTA Tour’s most popular player for four straight years (2011-2014), begins her new season January 5th in Sydney, Australia.
