Andy Murray hopes the return of Ivan Lendl to his coaching team could be the spark he needs to finally ignite his season.
The world number one is only ranked 17th in the world on 2017 form, with just one title to his name from Dubai in February.
He arrives at the French Open admitting he has struggled for motivation in recent months but claiming he is now ready to turn the corner ahead of his Wimbledon title defence in July.
Coach Lendl has been absent from his corner since the Australian Open but will be back in the players' box at Roland Garros when top seed Murray faces Andrey Kuznetsov on Tuesday.
"I do think in this situation, because I've been struggling, that having someone coming in with a fresh voice and a different set of eyes can give you new perspective,” said Murray.
"He's been through some struggles in his own playing career and he understands how to get out of it. All that experience is invaluable and he can definitely help me with that.
"I have been training as well as I could the last few months but it’s just maybe in a couple of matches it’s just been a little bit flat."
Murray will be the second match on the Philippe Chatrier show court following British women's number one Johanna Konta, who is looking to reach the French Open second round for the first time against Chinese Taipei's Su-Wei Hsieh.
British number two Kyle Edmund is also in action on Tuesday against Portugal's Gastao Elias, the world number 125.
If he wins that he could set up a clash with home favourite Jo Wilfried Tsonga in the second round, though he has failed to reach the third round in his last seven tournaments.
Aljaz Bedene continued his recent impressive form on clay as he progressed to the second round with a 6-4, 6-0, 3-6, 6-1 win over American Ryan Harrison,.
The British number three dropped out of the world's top 100 in March but has won two challenger titles on clay and reached the final of the ATP Tour tournament in Budapest, moving back to 52nd in the world.
He dominated his rival, dictating play and underlining why this surface - where he has won 11 of his 14 tournament - is his best.
