Transfer-target Jordan Kadiri scored his second goal of the season when he grabbed the match winner for Ostersunds FK against Falkenbergs FF.
Kadiri, whose bid from Manchester City owners has been rejected by OFK as first reported by SCORENigeria, headed the winning goal in the 59th minute.
It was a clever glancing header from outside the six-yard box.
Last season, the former Sunsel FC star scored thrice for his Swedish team.
OFK are now 12th on the table with seven points from as many matches.
They next welcome Malmo on Thursday.
