The hosts had gone ahead in the ninth minute through Ahmed Jimoh’s strike from a good use of a defensive error by the Naze Millionaires in the week four encounter.
Kwara United’s lead however only lasted for just three minutes as Mohammad Mohammed equalised for the visitors after they perfectly finished off a fantastic team play.
Mohammed was then to sustain an injury from a bad tackle at the far edge in the Kwara United half of the pitch and was replaced by Jimoh Oni.
Oni only spent a few minutes before putting the visitors in the lead in the 21st minute, capitalising on another bad defensive display from the host team.
Former Flying Eagles star Bright Ejike made it 3-1 for Heartland FC in the 29th minute, after John Ibe had dribbled through a porous Kwara United defence.
The News Agency of Nigeria (NAN) reports that Heartland have now won three of their three games since the start of the season.
