Steve Bruce insists he will "protect" star Sean Longstaff's midfielder, who has gone from £ 50 million in Manchester United's summer goal to Newcastle's replacement.
The young midfielder had a summer of clamor around a potential passage at Old Trafford, while he was recovering from a serious knee ligament injury.
The interest of Manchester United came after Longstaff made only 13 starts after joining Rafa Benitez's team last Christmas.
Bruce believes that Sean, who is close to the agreement for a new contract of £ 80,000 a week, and brother Matty, who is also ready for a first turn in the team, are "rooted" and will not lose their way.
Bruce said: "All this is that (hype) it usually sends you up here (points to the roof). There are times when you just have to protect him but, of course, the only thing I liked about him is that he didn't like being on the bench. He certainly reacted in the right way.
"Sean and his brother are rooted individuals. They are a breath of fresh air, the two brothers, and it will not be long before the other brother (Matty) arrives there. I think this will help to be well rooted.
"Of course, in the back of my mind, he had a serious knee injury, so in this way, I have to protect him a little, that's all.
"I think there have been moments in training and also in the last three or four weeks that his knee was sore and not as fluid as you would like to be.
"He had a serious knee injury and there are times when he was just a little short and that he was in pre-season games and looking at him in training."
Longstaff is teaming up for Sunday's trip to Spurs, where Bruce admits that he needs a "siege mentality" and a "great performance" to match one of the best teams in Europe.
A third defeat would be harmful and Bruce said: "Some players have been here for a long time. I think they know the club's expectations and what it should be, but this is the fabric of a big club: you have to perform.
"You are in the spotlight and nobody is in the spotlight any more than we are at the moment. The only way we can change things is to put together a good performance, we hope to get a result and start putting together some performances and back-to-back results, which will get us going again ".
With the clashes against Leicester in the Carabao Cup and Watford at home, he added: "It's a big, big week, but we hope to start with a performance on Sunday.
"For an hour, 70 minutes, against the Arsenal we gave up. We made a mistake for the goal that eliminated the wind from the sails, but we need a performance and we hope it's the right kind of game we need.
"In Norwich, sometimes individually and collectively, sometimes you can't play well. We do not all intend to do it, but on the biggest stage of all I remember having personally had a nightmare in the Camp Nou one night. I didn't want to do it – I was absolutely hopeless – so don't intentionally go out there to be poor on that day.
"What you need to do, though, is make sure you don't accept it and do everything you can to make it right
"Nobody gives us a squeak of Spurs. It could be the right game to say: "Come on, then, let's see what we have and let's go."
