Rome Masters Djokovic battles past Koepfer to reach 11th Rome Masters semi-final AN HOUR AGO

Djokovic has already said 1992 Wimbledon champion Agassi will be at the All England for the duration of the third Grand Slam of the season which begins on Monday after the American advised him for the early part of the French Open last month.

He is seeded second at an event he has won three times over the past six years.

Ancic is a former world number seven who won the Davis Cup 12 years ago while he also reached the last four of Wimbledon in 2004.

He was forced to retire at the age of 27 before moving into the world of banking as a financial advisor with Credit Suisse in the USA.

Ancic has apparently accepted Djokovic's call to help at Wimbledon, but according to reports will not be giving up his job to help Djokovic on a full-time basis.

Djokovic is due to meet Gael Monfils in Saturday's Eastbourne final after the second seed beat Richard Gasquet 6-2 6-7(7) 7-6(4) in an all-French semi-final showdown.
