Celtic's star players have to convince boss Gordon Strachan of a first team place. Strachan has told the Hoops disgruntled stars they only have themselves to blame if they are being left out of his starting XI.
He said in the Evening Times: "People have to remember, I watch training every day, and I notice players who are working well.
"I hear some saying, 'I'm not getting a chance'. Well, you do get a chance. I see you every day. I see your fitness. I see your commitment, I see your mental strength, I see your drive.
"I have never missed training since I came here. I make sure I see every session. And I can sniff out if players are at it or not."
