There will be plenty going on “behind the scenes” at Newcastle United as the club try to tie down the Longstaff brothers to new contract.

That is according to Alex Bruce, the former Premier League defender and son of the Magpies manager Steve Bruce, speaking exclusively to Football Insider.

The midfield duo’s Newcastle careers are in doubt, especially that of younger sibling Matty, who is out of contract in the summer.

Sean is out of contract in two years and his future is also up in the air after Man United made moves to sign him last year.

Asked by Football Insider about the importance of Newcastle keeping hold of the Longstaff brothers, Bruce replied: “It’s important, no doubt about it, Dad will want them to stay. Geordie lads, the supporters will want them to stay but I think there’s always a ceiling in everything.

“It depends what they’re asking for, depends what they’ve been offered at other clubs, a lot of things go on behind the scenes that people don’t really know about.

“But, if you’re asking me plain in black and white would he want them to stay? Of course he would.

“If they’re asking for stupid money or they might want to go abroad, they might want to leave, they might want something new – you never know until you speak to an individual themselves.

“Dad’ll be hoping he can tie them up but there will be a lot of things going on behind the scenes.”

Matty Longstaff, 20, has made six Premier League starts among 12 appearances for the Newcastle first team, announcing his arrival with the winning goal on his Premier League debut against Man United.

Sean Longstaff, 22, is more established Bruce’s side and has made 13 league starts among 26 appearances in all competitions this season.
