Malmo's official website crashed after news that Zlatan Ibrahimovic, who started his career at the Swedish champions, will return in the Champions League with Paris Saint-Germain.
After beating Scottish champions Celtic to make the group stage, Malmo were drawn in Group A with Real Madrid, Shakhtar Donetsk and PSG.
"There was a lot of pressure on [the website] just after the draw was made," Malmo's head of communications Peter Ahlander told Reuters.
Ibrahimovic has never won the Champions League, despite playing for the likes of Ajax, Barcelona, Inter Milan, AC Milan, Juventus and PSG.
