Former Celtic ace Harald Brattbakk helped Rosenborg to win 10 League titles in a row, but the highlight of his career remains denying Rangers their own famous 10.
The ex-Norway striker still keeps an eye on Scottish football and is watching closer than ever this season, when his former club will become either the first Scottish team to win 10 titles or the third to fall at the final hurdle.
In the 1960s-70s, Jock Stein's side ran out of steam after an historic nine-title run - which also included a European Cup - while Brattbakk was one of the Celtic heroes in 1998, when Walter Smith's Rangers were denied a famous 10 on the very last day of the season.
Celtic were two points ahead of a stuttering Rangers, and goals from Henrik Larsson - in his first season with the club - and Brattbakk saw off St Johnstone at Celtic Park to spark riotous scenes in the west end of Glasgow and all over the world.
"When I arrived late in 1997, I was not too aware of the situation of stopping 10 in a row, I really didn't feel that pressure at first," Brattbakk said. "It was only when it came to the last few games that I really considered what the options were.
"It's rewarding to have won so many titles with Rosenborg, but everything around that game, that title in 1998... well, it's still the most special thing I've been through in my career. I've never seen emotions run so high, anywhere.
"It also comes with the size of the club - it's huge on a worldwide basis. I've been fortunate to win titles, play in the Champions League, and for and against good teams, but that experience of '98 comes out on top of my list.
"Everyone asks me what I remember from that day - but it's nothing! I was focusing on the job at hand and there was a huge party afterward, so it's hard to remember.
"I watched it over again not too long ago, it's still fun to watch."
Having won 10 and stopped 10, Brattbakk is in a unique position to comment on the task at hand from both sides.
For example, which is easier?
"It's easier to stop 10," he said, without hesitation. "It only takes one chance or one shot to win one title, but to win 10 you need to perform at your best for 10 years. That's a much, much bigger achievement.
"Having said that, winning 2-0 against St Johnstone and stopping Rangers from getting 10 - it might be easier, but it was better.
"If Scott Brown gets 10, that feeling might be better... but he has nine already, and just denying someone like him a 10 can be an even more special feeling. It's complicated."
Northern Ireland hitman George O'Boyle almost scored for St Johnstone against Celtic minutes before Brattbakk's clincher in 1998, highlighting the fine margins involved that season, and the Norwegian insists there's still a long way to go this campaign.
In '98, Celtic had lost four games by this stage of the season, while Rangers lost just once before the New Year's Old Firm derby at Celtic Park.
"I came in December and we'd lost a few games so it's hard to think anything is decided just yet," he said. "In January, or close to February, you'll get a better idea, and the games will all become more important.
"It's mostly now about how the players handle the pressure, and the experienced players, like Scott Brown, will need to ease things for the younger players."
Hoops boss Neil Lennon is under fire from the club's fans following this season's stuttering start, but the ex-Northern Ireland midfielder insists he will not panic despite falling 11 points behind leaders Rangers.
Brattbakk agreed that keeping cool is key: "The manager (Nils Arne Eggen) was instrumental in Rosenborg getting to 10 titles, and one of the best things he did was in the summer of 2001, when we were starting the '10 season'. We were a bit behind early on and when we came back from the summer break, we expected things to change.
"But the most important thing was how he went on as if nothing had happened... the sessions remained the same, nothing different off the pitch, we just focused on the next game, next win, next tackle. It was about being confident in what we knew."
