View the photos from the latest Blues victory
Pompey battled from behind to beat Coventry 2-1 at Fratton Park and move up to third in the League One table.
Jordy Hiwula swept the visitors ahead in a first half that saw plenty of chances created at both ends of the pitch.
But the Blues looked a lot stronger after the break and levelled when Lee Brown's corner was firmly headed home by Tom Naylor.
And the turnaround was complete late on, as another set-piece was not properly dealt with, allowing Brett Pitman to fire into the net.
