Brown banned for Hoops
Skipper Scott Brown is suspended for Celtic's Scottish Premiership clash with Dundee at Parkhead on Saturday.
The Scotland captain, who signed a new four-year deal with the champions on Thursday night, was sent off in the Hoops' 2-1 win at Aberdeen before the international break and will serve a one-match ban.
Defender Mikael Lustig will be out for several weeks with a hamstring injury but Kris Commons has recovered from a buttock injury.
Stefan Johansen believes Celtic will continue to improve now they have worked out Ronny Deila's demands.
The 23-year-old midfielder personifies the transformation in form at Parkhead from the start of the season when the Hoops struggled under his fellow Norwegian who, after taking over from Neil Lennon in the summer, came under intense scrutiny after two chances at qualifying for the Champions League were missed.
Johansen, who played under Deila at Stromsgodset before moving to the Glasgow club in January, has arguably been Celtic's best player in recent months, playing in a more advanced role.
His third goal in six games before the international break helped the champions to a 2-1 win at Aberdeen and meant the Hoops have lost only one of their last 15 matches.
Ahead of the visit of Dundee, the Norway international promised more improvement.
"I am enjoying my time, and starting to score goals in a kind of new role," he said.
"There hasn't been anything wrong with my fitness or anything like that.
"It took time with me and it takes time with the team.
"We are winning games and starting to create a lot of chances but I think we can be even better.
"At the start of the season we had a new gaffer who had new ideas.
"I think we are starting to see what he wants in the team. The players know what to do now so it is going to be easier and we are going to be better and better."
Dundee manager Paul Hartley insists his side will not roll over against the champions.
The Dark Blues are on a four-game unbeaten run and will look to extend that as they go up against Deila's league leaders.
Hartley had a successful time as a player with Celtic but will put all sentiment aside in his efforts to help the Tayside club earn a positive result this weekend.
Hartley said: "I'm looking forward to going to Parkhead.
"It's a first-class arena and I've not been there since 2010 as a player. So I'm looking forward to going back there as a manager.
"It's the kind of place where you want to go and play your football. So I hope it brings out the best in our players on the day.
"We've prepared well all week and want to show that we're a good side, so we'll certainly have a go rather than just stand back and watch Celtic."
Dundee drew 1-1 with Celtic back in September and Hartley reckons their showing that day in front of the live cameras should give them plenty of confidence going into this fixture.
He said: "We played well that day. I was pleased with the players for their efforts, as I have been all season.
"We matched them and could have won the game towards the end. You know you have to take chances when they come your way against a very good team like Celtic.
"They are starting to play a style which their manager likes but we'll obviously have to look after ourselves.
"We're on a decent run of form just now. We want to keep that going and believe we can.
"I might make some changes to the personnel but whoever starts we feel is capable of doing a good job for the team."
Meanwhile, Dundee defender Paul McGinn is doubtful with a back injury while winger Martin Boyle has flu.
Striker Craig Wighton (ankle) is struggling but midfielder Simon Ferry and forward Luka Tankulic will both be back in the squad.
