Andy Murray is reuniting with his former coach Ivan Lendl two years after they parted company.
Eight-time major champion Lendl guided Murray to his two Grand Slam titles and Olympic gold in 2012 and 2013.
Murray's main motivation for the rehiring Lendl is, surely, to try to help him break the stranglehold of Djokovic, who holds all four grand slam titles after beating Murray in the finals of both the Australian and French Opens.
A two-time Grand Slam champion, Murray has now lost five major finals to Djokovic, and another three to the great Roger Federer.
Lendl will be with Murray for the Aegon Championships at Queen's Club, which starts on Monday.
Murray has been the flag-bearer for British tennis in recent years as he became the first Brit in in 77 years to be crowned Wimbledon champion back in 2013.
Tim Henman believes Novak Djokovic remains the clear favourite to win Wimbledon despite Ivan Lendl's return as Andy Murray's head coach When he agrees to do something, I think he goes in 100 per cent.
They will pair up for Murray's defense of the Queen's Club title later this week then the grass court grand slam at Wimbledon.
'I enjoyed working with Andy in the past, ' added Lendl. "I know what he can offer".
Murray's decision to split with Lendl originally came because the 56-year-old former number one was unwilling to spend extra time with Murray on the gruelling ATP Tour.
"There's not a time-frame on it, but I would like it to continue as long as possible", Murray was quoted as saying by AFP.
The Czech is also associated with the United States Tennis Association's player development programme but it is hoped that he would still be able to devote enough time to Murray during the major tournaments, important training blocks and even a few Masters events.
Murray went on: "I think the most successful period of my career was while I was working with Ivan".
What Murray needs most is mental discipline if he is to catch the superior Serb, and Lendl can provide it after conquering his own nerve-ridden uncertainties on and off the court.
"I'd never done that well on clay before so I needed to let my body rest and recover a little bit before I started practising on the grass again", he said.
Jamie Delgado will remain part of that team.
"I've played a lot of tight matches, quite a lot of long matches, so physically I'm not so concerned".
