Mika Baur has urged Celtic to focus on winning rather than style in this weekend's fixture against Rangers.
The midfielder, who scored his first European goal for Celtic against Ferencvaros after a Germany call-up, watched his team fall to a 3-1 defeat on Thursday. This was Celtic's second consecutive loss following a 3-0 defeat at Ibrox.
Baur believes the team should concentrate on their mentality instead of tactics to bounce back. He said: "We will not win it through beautiful football and nice plays. We will win the game on Sunday with mentality and energy.
"That's what everybody should bring into the match on Sunday."
The German international-elect said last weekend's loss did not reflect the true Celtic, and encouraged his team to regain their form.

He added: "That was not us last Sunday, so it's more about getting back to ourselves, getting back to the winning streak and just take the win and get three points."
Baur also asked for support from the Celtic fans, with 60,000 expected at Celtic Park. He said: "You can feel that it's a special game. There will be 60,000 on our side. So we should use that.
"We need everyone. We players will give 100-per-cent on the field and we need everybody else to get that energy back and win on Sunday."
Despite his Germany call-up this week, Baur remains focused on the upcoming game. He said: "It's a big honour and I'm really proud of it.
"But it's all about Sunday. It's really important for us, for Celtic."
