Aaron Mokoena's first league goal in English football helped Portsmouth to a second npower Championship victory in five days by seeing off Bristol City 3-1 at Fratton Park.
The South Africa international, who joined Blackburn from Belgian club Genk at the start of 2005 before moving to Portsmouth last summer, thumped home a header after 58 minutes to restore Pompey's lead.
It was the third goal in an action-packed eight-minute spell.
John Utaka put Portsmouth ahead in the 51st minute but the lead was short-lived as Jon Stead equalised two minutes later.
After Mokoena's goal, Hayden Mullins sealed the win on the break in the fourth minute of injury-time.
Following the 6-1 demolition of Leicester on Friday night, victory gave Pompey back-to-back home wins for the first time since December.
