Kamara struck the equaliser against the Bulgarian league leaders in Thursday night's Europa League fixture, picking up Erik Nevland's pass and rounding goalkeeper Ivan Karadzhov before finding an empty net.
It was his first goal of the season, cancelling out Michel Platini's opener and marking the end of an unsettled period that saw him linked with a move to Newcastle.
Roy Hodgson: "Diomansy took the goal very well. We've see him do that so many times.
"When he span away I was confident he would get behind the defence and compose himself. It still wasn't an easy finish - it was on his left foot as well.
"It's once of those goals where you think 'open goal, he should score' - but I've seen many missed in my time.
"There's no truth in the stories that he's going to Newcastle.
"Just before the transfer window closed, Chris Hughton contacted me and asked if it was a possibility - and I said 'no'.
"Three or four days later, someone else at Newcastle asked our board if there was a chance they could take him on loan.
"We said no - because we need him for the European games."
