Scott Brown has warned SPFL defenders that Leigh Griffiths has been in frightening form in training.
Griffiths is expected to be on the bench against Hamilton today after weeks of comment about his attitude and approach to the game.
Brendan Rodgers recently spoke out about his frustrations with Griffiths who has suffered a series of hamstring and calf injuries throughout the season.
The Celtic boss questioned whether the former Hibs striker had the dedication to realise his potential.
In midweek Brown and Griffiths watched Hibs knock Hearts out of the Scottish Cup with the hoops skipper delighted by the striker’s response to a public dressing down.
“The wee man has been frightening in training this week,” Brown told The Sun.
“That’s him back now, and I know what it’s like when you get injuries then pick up another one, just when you are coming back but he is looking sharp and chirpy, so it will be good to have him back in the squad.
“It’s all down to the squad here. If you are not playing well the gaffer can easily chop and change it. He is strong-willed that way, and it doesn’t matter who it is, or what position you play.
“There are other players who will listen and do their job, so if you are not working hard on and off the field, the gaffer will put in someone who is.”
In 10 Premiership starts and five substitute appearances Griffiths has scored eight goals this season but his biggest contribution came in the Champions League qualifiers.
Against Astana in the third qualifying round he scored home and away as Celtic got through on a 3-2 aggregate before a first half double in the 5-2 win over Hapoel Beer Sheva took Celtic to the brink of the group phase.
