Steve Bruce gave Matty Longstaff his Premier League debut in Newcastle’s last match, and the teenager made the headlines as he blasted home the winner against Manchester United.
The younger Longstaff brother is starting to make a name for himself at St. James’ Park now.
And Sean admits that he has been very impressed by how well his sibling his taken to life in the first-team.
"There's a reason why the manager has him up with us. He's been brilliant in training every day. He has the quality and the composure,” Sean said.
"You could see against Man United just a minute into the game he was pinging diagonal balls from 40 or 50 yards.
"It's great to see because he breeds confidence around the team.”
Sean and Matty could start again for Newcastle at the weekend, with Bruce unlikely to make many changes from his side’s last match.
Newcastle are due to take on Chelsea, where they will be looking to cause an upset.
The Longstaff brothers were combative and energetic against United, and if Newcastle are to pick up any points from London they will need to put in a similarly high level of performance.
Chelsea have been in good form recently, and head into Saturday’s game as heavy favourites to pick up the three points.
