Celtic legend Martin O'Neill has fired a warning to new Rangers boss Philippe Clement, saying the Ibrox boss must "win immediately".
The Belgian has joined the Light Blues on a three-and-a-half year deal and O'Neill was keen to address comments the 49-year-old made in his first interview after landing the role.
Clement spoke about things "taking time" at the start of his managerial process and the importance of inputting style of play.
And the former Parkhead manager made clear that Clement must bring instant success otherwise he will be under pressure.
Speaking to talkSPORT, he said: "Just win some football matches. You have to overtake Celtic, it’s as simple as that. That’s what you have to do.
“You need to do that relatively quickly. That’s the point – none of this, please don’t come in and say ‘you have a three-year plan or I want to see the youth players developed’, which I think he might be able to do.
“But, no, you have to win. And you win immediately.”
Meanwhile, Celtic midfielder Matt O'Riley has opened up on the "strange" nature of his international call-up for Denmark.
The 22-year-old has joined the senior squad for the first time ahead of their clash against San Marino after Kasper Dolberg pulled out.
And O'Riley revealed he was in Spain at the time when the call came. Speaking to Bold.dk, he said: " It happened very quickly. I just got a call from Morten Wieghorst and Kasper Hjulmand.
"I was just sitting in Mallorca and eight hours later I was in Denmark, so it all happened very quickly. Wieghorst said that there was a very good chance that I would go and then I had to pack my things and be ready.
"I also had to talk to the hotel reception and say that I had to check out, but the feeling you get with that is really good!
"It was a bit strange. After all, I wasn’t sure if I should hide my face or not. I didn’t want anyone to talk about it, so I chose to wear a hat and hood."
