Former Celtic star Paul Lambert has opened up on his relationship with Rangers hero Stefan Klos and recalled scrapping on the Ibrox pitch with the German in a bad-tempered Old Firm clash in September 2001.
The pair won the Champions League together with Borussia Dortmund four years earlier but Lambert admitted that the fracas between the pair was “ridiculous” given their friendship.
Klos and Lambert wound up rolling around the penalty box at Ibrox and they ended up burying the hatchet afterwards with a phone call between the pair.
“I went through everything with Stefan. We were great friends and had won the best club trophy in European football. You don’t get any higher than winning a Champions League and we had those great moments together at Dortmund,” Lambert said, as quoted by the Daily Record.
“Fate brought us back together in Glasgow but on opposite sides of the city. He was out there to do his best for Rangers and I was exactly the same at Celtic.
“You don’t have friends on the pitch when you’re playing. It doesn’t matter how friendly you are away from the game, when you cross that white line, the guy on the other side is trying to beat you and you have got to be just as desperate to beat him.
“It’s win at all costs. At that level winning the game is all that matters. If you can do it in style, like we did in that 6-2 game, fine. But to be honest in games against Rangers, you couldn’t care less if they were the better team as long as you came off the pitch winning.
“What happened that day was ridiculous and proves anybody can get caught up in it. I remember after the game I was in the car and one of us phoned the other. I genuinely can’t remember who made the call but I remember the conversation.
“Stefan said to me: ‘what the hell was that all about?’ and we were at a loss to explain it. The emotion of the game, the adrenalin that flows through you… it makes you take leave of your senses at times.
“Stefan is a quiet man and doesn’t get easily ruffled and yet he and I were rolling about the six-yard box. It was mental but that game does things to you.”
Klos spent nine years at Ibrox and retired after he moved on from Rangers in 2007 following an injury which cost him his place in the Gers starting XI.
During his time at Rangers, Klos lifted four Scottish titles, three Scottish Cups and two League Cups to add to two Bundesligas and Champions League title he won in Dortmund.
