Add Martina Navratilova to the growing list of past tennis greats signing up to coach today's top players.

Navratilova will be working with Poland's Agnieszka Radwanska, the 2012 Wimbledon runner-up and No. 6 in this season's final WTA rankings.

Both women tweeted Monday about the partnership, with Radwanska referring to Navratilova as "the newest member of my coaching team."

Navratilova, who won 18 Grand Slam singles titles as a player, wrote she is excited to work with Radwanska "and her team" and that it "should be a fun ride."

They join the recent trend of players hiring former stars as coaches, including Andy Murray bringing aboard Ivan Lendl and then Amelie Mauresmo, Novak Djokovic with Boris Becker, Roger Federer with Stefan Edberg, Marin Cilic with Goran Ivanisevic, and Kei Nishikori with Michael Chang.
