Kenyan internationals, Eric Johanna and David Ochieng both made their debut in the Swedish top flight with a victory on Sunday.
Johanna announced his IF Brommapojkarna arrival with a goal in a 2-0 win over Ekilstuna in a friendly match.
Johanna joined Brommapojkarna from IF Vasalund who were relegated to the third tier league last season while defender Owino completed a move to the side early this week from New York Cosmos.
The Harambee Stars midfielder, Johanna also provided an assist against the second tier side in a pre-season match.
Johanna, a former mathare United player, scored in the 29 minute, just nine minutes after he had set off Nieves Maikel for the opener at Grimsta Stadium in Stockholm on Sunday.
