Meanwhile, Great Britain's hope will be pinned on Murray, who has made the finals three times, but failed to lift the trophy on all three occasions losing to Federer in 2010 and to Djokovic in 2011 and 2013. The Scot has been handed a tough draw and will have to get past Federer and Nadal to make it to the final, if the trio win all their matches in the previous rounds.

Serena Williams will come in as a pre-tournament favourite owing to her fine form in 2014, with Maria Sharapova being her closest challenger.

Li Na who won the grand slam in 2014, has retired from the game and will not be present to defend her title and 2012 and 2013 champion Victoria Azarenka has dropped down the rankings and is unseeded for the tournament.

Canadian Eugenie Bouchard will be a player to watch out for after a breakthrough performance in 2014, which saw her reach the semi-finals at the Australian Open and the French Open and make the finals at Wimbledon.
