Danny Mills says that it was “incredible” to see Newcastle United midfielder Matty Longstaff score the winning goal against Manchester United on what was his Premier League debut.

The former Leeds and England defender, speaking exclusively to Football Insider assistant editor Russell Edge, admits there are few better sights than a young player flourishing at his boyhood side and that having brother Sean alongside him in the midfield made it an extra special occasion at St James’ Park.

The 19-year-old was handed a surprise start by manager Steve Bruce on Sunday and the teenager rewarded his faith with a low, driven strike past David De Gea to seal a 1-0 win.

Mills says that it was a wonderful sight at St James’ Park but that the teenage talent needs to stay grounded and ensure he continues to perform on a consistent basis after his dream start.

Mills told Football Insider: “It’s fabulous whenever a young player comes through, does well and all goes well. It’s fantastic, it’s what dreams are made of, especially scoring on your debut against Manchester United.

“That is incredible, to play alongside his brother as well, I’m sure the family were very, very proud of that whole situation.

“It’s great to see, the secret is to do it week in, week out and not get carried away by one performance, one shot. He’s got to deliver this on a regular basis, time after time.”

Sean Longstaff emerged as a favourite of former manager Rafael Benitez last season and played nine times in the Premier League before injury cut the 21-year-old’s campaign short.

His brother made his competitive debut in the League Cup defeat to Leicester City before lining up alongside Sean for Sunday’s dramatic win.
