Emil Forsberg's second-half penalty sealed Sweden a 1-0 win over Slovakia in Saint Petersburg on Friday as the Scandinavians moved top of Euro 2020 Group E.
Janne Andersson's men, who played out a goalless draw with Spain in their opener, now look set to reach the knockout stage for the first time since 2004.
On Friday, Sebastian Larsson had an early effort comfortably saved by Martin Dubravka, but Slovakia otherwise started brightly, with Juraj Kucka heading wide in the fifth minute.
Kucka drew a brilliant one-handed save from Robin Olsen, but the Slovakia midfielder was flagged offside.
Slovakia laid a late siege on their opponents' goal, but saw an optimistic late penalty appeal for handball turned down as Sweden held on.
