Sunday night's match was played away and Mamudu Moro secured all three points for Mjallby by scoring the only goal against Malmo FF.
When Mjallby's players stepped out on the pitch for the last pass before the big match, they were met by a roaring cheer from the stands.
The pandemic restrictions have been lifted in Sweden and during the weekend football stadiums were filled to the brim for the first time in a long time.
In Mjallby's coaching staff, it was thought that it could cause problems in Sunday's away match against Malmo FF after players playing in an empty stadium for a long time.
Mamudu Moro scored in the 15th minute for Mjallby while compatriot Enoch Adu came on in the 81st minute.
