One point currently separates bottom-placed Sunderland and Cardiff, who are two points away from safety with three games left to play.
"If you look at the league table, it's just as big for both of us," Solskjaer told reporters. "It is still so tight down at the bottom that a win will be hugely needed for both of us, while a draw is probably no good for either of us.
"I wouldn't be in football if I was nervous. You have to look forward to games. I used to do that as a player, and I do that now. The waiting time is the worst."
After facing Sunderland, the Bluebirds will play Newcastle United and Chelsea.
