"I played in all the games in 1999 and was out for nine months or something," said the Norwegian. "I kept playing in 1999 even though I had 'jumpers' knees' problems with my patella tendons and I needed an operation on both of them. It took me a while to come back but I came back just in time to win the league again which was quite funny!
"I think the Treble is something very special. So many times, we came back from 1-0 down because we had that belief and the ability to win it. It was a very, very special season for us and, of course, for the club as well."
Imposing centre-back Stam also looks back fondly on that magical campaign as he was another key member of the side. "It is very hard to do it. Sometimes, of course, you need a bit of luck as well. At the time, like now, we had a great team and we were working very hard for it in every game we played.
"We did need some luck during the games but, if you go for it as a team and all the players and everybody has got the mind-set on what to achieve as a team, and also for yourself as a player, I think you can do many things in life and also football. It was one of our strongest points - everybody was very eager to win the trophies, work hard for it and never give up. Even if we were 2-0 down to Juventus [in the second leg of the Champions League semi-final], we kept going and achieved a good result at the end of the game. I have only happy memories from that time."
