Celtic manager Neil Lennon has voiced his concerns over the early start to the new SPL season.
Lennon is worried about the effect that the short break will have on his players' mental condition when they travel to Hibernian on Sunday.
"We finished on the 21st of May and we were back in on the 23rd June and the season is starting on Sunday," he said. "Some of my players have had a fortnight's break.
"Physically they are alright but you wonder about mental fatigue kicking in, maybe not early in the season but maybe later on in the season so we have to be wary of that."
