Thomas Bjorn has admitted to being fearful that his European Ryder Cup stars will be suffering from physical and emotional fatigue after this week's Tour Championship at East Lake GC.
With only one week until Paris hosts the 2018 Ryder Cup, the Dane has told the BBC's The Cut podcast that he is wary of his players being exhausted by a week of high drama in the PGA Tour's FedEx Cup finale.
"I always think the FedEx Cup can be a bit hard with the Ryder Cup coming straight after it for those guys doing really well," he said.
"You've got to time manage them, you've got to manage their energy levels and they have got to be very good at looking after themselves for what is a very tough and hard period."
Bjorn will be excited that his team heads to Le Golf National with the newly anointed world number one Justin Rose, but he is aware that the Englishman has finished second in his last two starts and fully intends to be in contention again this week.
"Emotionally they go through a lot of things," said Bjorn. "And when you get to world number one, you have got to look after yourself and keep pushing through the next few weeks.
"Justin's a full-out professional and you can be very sure that he is capable of doing that. You've got to take all the positives from one of your players going to world number one."
In all there are six Europeans playing in Georgia this week. The others are Rory McIlroy, Open champion Francesco Molinari, last year's Race to Dubai winner Tommy Fleetwood, Jon Rahm and Paul Casey.
Whilst Bjorn is concerned about Rose hitting the heights, he will have less fears if Casey or Rahm do so. In fact he's probably keen that the pair rediscover a bit of form because neither has made a top ten in the last five weeks.
Rose is 8/1 to win the Tour Championship, while McIlroy is 8/1, Molinari 22/1, Fleetwood 25/1, Rahm 25/1 and Casey 40/1.
