Newcastle United captain Jamaal Lascelles says Matty Longstaff's breakthrough is exactly what the club needed.

The 19-year-old academy graduate had a debut to remember against Manchester United, scoring the winning goal in the 1-0 victory at St. James' Park.

"I'm buzzing for him since he's come into the squad. Everything we do, he is up for it. He's fit, he works hard and always gives extra," Lascelles told Sky Sports News.

"The hard work has recently paid off, he's been thrown into the deep end like his brother.

"What you do know is that he is a young Geordie lad who is going to roll his sleeves up and play with his heart.

"Straight after the Leicester game we needed players to be like that, he was a prime example of what you can get from that. His goal got us the three points, I'm over the moon for him."

"You see all these big teams signing players for millions of pounds from overseas and everywhere else, Matty was not long ago training down with the reserve team.

"He's just come up through the ranks and grabbed a first team spot with two hands.

"He's humble, a very nice genuine lad. It must mean the world to him."
