Four Hoops stars have been selected for Strachan's first Scotland squad for next week's friendly with Estonia but the new boss says Parkhead manager Neil Lennon trusts him implicitly with his players.
"I have spoken to Neil Lennon about that.
"He said to pick the guys I want. He trusts me to look after them, to do the right thing for Scotland and Celtic.
"I have free rein to do whatever I think is right.
"I have never interfered with international managers when I was a club manager because I know the players want to go."
