Celtic defender Thomas Rogne is not worried by the club's failure to win their last two outings.
The Bhoys followed up defeat in the Scottish League Cup final against Kilmarnock by losing to Rangers in Sunday's Old Firm clash.
Rogne is happy with Celtic's big-game experience and the Norwegian insists Neil Lennon's squad relish the pressurised matches.
"We have played big games before and won them," commented Rogne.
"I don't think that it's a mental thing. Going into big games is not a problem for us, it's something we all look forward to.
"Of course we were disappointed with the last two games.
"We wanted to win them but sometimes it happens in football that you lose important games. It's part of the game.
"We are just looking forward to turning it around again."
Celtic had Cha Du-Ri and Victor Wanyama sent off at Ibrox on Sunday and Rogne felt Cha's red card was harsh.
Cha was tracking Lee Wallace's run and the 21-year-old believed the South Korean was not the last man as Charlie Mulgrew was covering.
"I haven't seen the situations again but I think the first sending off was not a sending off. That's what I felt out there," he continued.
"It's a very difficult job for a referee and things happen so quickly and he sees a man going down.
"But I'm not sure it was the right decision. First of all, I didn't think it was a free-kick, I don't think he challenged and I don't think he touched him that much.
"I also thought that Charlie Mulgrew was covering him so he wasn't the last man.
"As I said, it's a very difficult job for the referee and I'm not going to criticise him too much because we know how difficult it is."
