Rafa Benitez has spoken to the media ahead of Newcastle United's game against Barnsley tomorrow night.
The club moved up to second place in the Championship after Saturday's 3-1 win over Brentford.
Barnsley, without a win in five league games, are in 11th place.
But United manager Benitez – whose side will be backed by almost 6,000 fans at Oakwell – feels it is a "dangerous" fixture.
Benitez also gave an injury update and spoke about the form of goalkeeper Karl Darlow and midfielder Jonjo Shelvey.
“It’s a feeling that we have confidence in the things we are doing at the moment.
"I have told the players this is a very dangerous game. It is a team that plays with high tempo. We can’t go there over confident believing we will win because the other teams are scoring goals, not conceding too many, but they are dangerous because they are scoring goals."
“Every player in every team has to realise that if they don’t play, the must keep working hard to change the manager’s mind. Karl was training well, Matz (Sels) is training well now. The competition is good for the team. They are professional, but if they have to be ready to do well.
“I can understand any player not playing will be disappointed (at not playing), but they have to respect the team-mates. They have to be sure they keep working hard and be ready when they are needed."
“A lot of teams have put a midfielder close to him, but for me he is doing well.
"I am pleased with the attitude, the way he is working with the attitude. If we are just depending on Jonjo then we are in trouble, though. The rest of the team has to do well, if he is not playing well then the other players have to do well and manage the game without him."
“(Daryl) Murphy has completed a full training session. Rob Elliot has trained with the keepers, (Jamaal) Lascelles and (Matt) Ritchie are both fine.
“You never know, but Rob is doing well. In two or three weeks he will be fine. He is doing well. I watched him a few days ago and he is fine. Good progress."
