The winger was simply unplayable as Rovers brushed aside AFC Bournemouth 3-1 at the Goldsands Stadium for their first away win of the campaign.
King had a hand in Rovers' opener as he found Leon Best who crossed for Jordan Rhodes to head home, and then won the penalty from which Rhodes scored to make it 3-0.
"Kingy is having the form of his life and we are delighted with that," said the Rovers boss.
"That has come about from his hard work on the training pitch.
"He's confident, we still want him to produce more end products but he's a constant threat to the opposition."
King and Rovers are back in action this Tuesday night when Watford are the visitors to Ewood Park.
