#4 Jimmy Connors
With 8 Grand Slam titles to his name, Jimmy Connors is considered to be one among the best ever to play tennis. He has also proved his mettle as a coach too, having coached the likes of Andy Murray and Eugenie Bouchard.
The American coached Andy Roddick, who was struggling to get out of the shadows cast by Nadal and Federer, for a 19-month period between 2006 and 2008 and also had a brief spell in charge of Maria Sharapova and Eugenie Bouchard.
Roddick enjoyed a period of resurgence under Connors’ charge, reaching the US Open finals once and the Australian Open semifinal before a spate of injuries laid him low. His work with Eugenie Bouchard has also been lauded.
The Canadian sensation had lost her mojo prior to the 2015 US Open when he worked with her for a while. She promptly reached the 4th round of the Grand Slam – a marked difference from earlier tournaments. Connors has done it all and certainly shown that he can improve players. Might well be a good option for Novak.
