Tonight, Sweden welcome Kosovo to Gamla Ullevi in Gothenburg looking to enact revenge after a shock 2-0 defeat in Pristina in September.
Defeat will not mathematically end Sweden's chances of returning to the FIFA World Cup, but the odds of losing this game and still making it to North America will be incredibly long, and will likely be the end of the Dane's time in charge.
But the pressure, Tomasson told the pre-match press conference, comes with the territory.
"As a coach, you can't sleep, it's a long night after a loss, but then you think about the next match. There's always pressure, but it's football."
The Blagult coach went on to acknowledge the fans' anger, conceding that this is also something to be dealt with when expectations are high.
"I understand that the fans are disappointed. Football is emotions and the audience wants the best for us. It's also black or white. You have to handle it."
A draw with Slovenia in September represents the only point in Group C out of a possible nine for Sweden. They sit bottom, a point behind Slovenia, while Kosovo are second on four points, while Switzerland are clear with three wins from three so far without conceding.
Neither of Sweden's star strikers, Alexander Isak nor Viktor Gyokeres, have scored so far in the qualification campaign, and they faced the media too to shoulder the blame.
"We players are clear and self-critical after matches where we don't win or perform well. I only hear players talking about that we haven't done enough good things. We look at ourselves in the mirror," said Isak.
Gyokeres added that it's the team who must deal with the issues, and would not lay the blame at his coach's style of play.
"In some of the matches, we haven't solved situations well enough and then I don't think it's about the way we play."
Liverpool's Isak echoed those sentiments, "I believe in the playing idea of being offensive is the right way, but you can have two thoughts in your head at the same time. We can be dissatisfied with the results, but it does not necessarily mean that everything is wrong," he outlined.
Sweden had been in brilliant form before this campaign, winning eight of their previous 10 games and gaining promotion in the UEFA Nations League, giving Arsenal man Gyokeres belief that their way of playing works.
"We saw last autumn that it worked. We created a lot and scored many goals."
"We still have three matches left and we have to make sure to do it right and win those matches," he added.
