Neil Lennon is more anxious than ever during the current international break with 35 of his Celtic players on duty with their respective countries.
The Celtic manager revealed that the club's Lennoxtown training complex is practically deserted with almost all of his senior squad and many of the Academy players missing.
Lennon admits it is a mark of the quality in his squad that so many have been called up by their nations but his pride is tempered by fears of potential injuries.
"It's right through the club now from Academy level all the way through to the first team," Lennon told the club's official website.
"I think we have 35 involved throughout the club which is quite a remarkable stat really.
"Whilst I would never stop anyone going and representing their country, it can be a very concerning time for me personally, just knowing if the players are going to be okay."
