Steve Bruce feels Newcastle United can be a "different animal" with Allan Saint-Maximin in the side after the Frenchman inspired a vital 2-1 comeback victory at Burnley.
Newcastle were second best and trailing to Matej Vydra's first-half goal before Saint-Maximin came on just before the hour mark. Within two minutes he teed up Jacob Murphy's equaliser and five minutes later he ran from the halfway line to score the winner himself.
The win lifted Newcastle six points above the relegation zone, and could prove to be a huge moment in their season.
This was only Saint-Maximin's 18th league appearance of a campaign hit by illness and injury and the Frenchman changed the way Newcastle could play as ponderous attacks turned into incisive direct play.
Saint-Maximin - who before last week's substitute appearance had been out since February - came on alongside top-scorer Callum Wilson, back after seven games out with a hamstring problem, and Bruce is hoping the pair can give Newcastle the attacking impetus they need.
"All week the question was, 'were they ready'," Bruce said. "They've had big injuries and it made sense to leave them out and see if they could make an impact and they've certainly done that.
"Probably only Allan could have done that and when you see games like that you see what we've missed. I hope we can keep them both well because we are a different animal with them in the team."
While Newcastle celebrated, Burnley were left to reflect on a second straight match where they could not convert a half-time lead into a result.
Sean Dyche's side had 24 attempts at goal and Martin Dubravka was much busier than opposite number Bailey Peacock-Farrell, drafted in due to a shoulder injury for Nick Pope, but there was no reward.
"It was a dominant performance and it's disappointing that you don't get anything from the game, but that's football," Dyche said.
