England scrum-half Ben Youngs believes a number of players will suffer from burnout next year after a busy World Cup season.
Youngs is currently in Denver with the rest of the England squad as they continue their preparations for the tournament on home soil.
The Leicester number nine reflected on the season following his involvement on the 2013 British and Irish Lions tour to Australia.
Noticing a dip in his form and enthusiasm, Youngs came back last season fresher and produced far better form.
Youngs now expects many players to suffer in a similar way either at the end of the 2015/2016 campaign or beyond.
“A big difference last season was that I had a summer off,” Youngs told the Guardian.
“In 2013 I came back from the Lions tour and I was straight back into action, playing in Jersey in a pre-season game. It was just rugby, rugby, rugby and it became a tough year.
"Time off left me hungry and refreshed the following summer and my confidence was up again, which is important for any player.
“People talk about player burnout and I switched off from rugby. I went away, took it easy and caught up with friends and family.
"Now we have another big period coming up: the World Cup will be followed by domestic rugby, the Six Nations and the tour to Australia. By the time that finishes, you will have three weeks off and your club will want you back.
"There is no doubt that in the next couple of years you will see some players suffer from burnout; I am glad I went through it when I did because there was not a golden egg at the end of it.”
