United travel to the Nou Camp needing to overturn a 1-0 first-leg deficit. It will be the first time Solskjaer has played or managed at the ground since scoring the winning goal for United in the 1999 Champions League final.
"[There will be] Many emotions, of course it's a fantastic memory for me." Solskjaer said. I've seen my Treble goal a million times - Solskjaer "I don't look back on that night too often. "I don't know how I will feel - I don't think it will be too different.
I am focused on a better performance. That is my job now. "Sometimes people have said to me it has to be our year because of 20 years ago and being back at the Nou Camp but to go through, we have to perform and have to deserve it.
We can't say we are just going to rely on fate." Solskjaer's goal against Bayern Munich came in the third minute of injury time, two minutes after Teddy Sheringham had equalised, and sealed a historic treble for Sir Alex Ferguson's side. Asked if the prospect facing his current side on Tuesday was more difficult, Solskjaer said: "In football, anything can happen.
"We know we can still be in this tie if we keep a clean sheet. In the 93rd minute, if we get a set-piece, we are taller and bigger than them. "We need to defend well and we need to score. I don't mind if it is in the 93rd minute." 'PSG win will help us' United are aiming to overturn a first-leg deficit for the second round in a row on Tuesday.
In the last 16, they recovered a 2-0 deficit against Paris St-Germain by winning 3-1 at the Parc des Princes to go through on away goals. Solskjaer said the win in Paris "will help" his team against Barcelona. "It will have helped us as a team," the Norwegian said. "We know we can turn things around. "Barca here at the Nou Camp is a difficult prospect but that night will live with the players. It was not that long ago and we are one goal better off [than we were then]."
