Dick Advocaat has told the Daily Star that he can see his Sunderland players growing in confidence by the day.
The Dutchman believes that the team's win over Newcastle United in their most recent fixture has lifted the spirits at the Stadium of Light, and the players have been much more confident since.
Advocaat says that even in training the players appear to have more belief in their ability, and that can only stand Sunderland in good stead for the future.
“I watched the game back and it has given the players a lot of confidence the way they performed,” he said.
“If they can continue to do that, it is good. And in training, I can see it is improving too. Hopefully, we can see that tomorrow against a very difficult team.”
There is renewed optimism around the Stadium of Light following their win over Newcastle, which has made their position slightly more comfortable.
The Black Cats are three points above the relegation zone as a result of their derby day success and they will have to protect this advantage over their remaining seven fixtures.
It means that having momentum on their side at this stage of the season could be crucial, and they will be determined to ensure that they build on their win over Newcastle.
The Black Cats can do this at the weekend if they beat Crystal Palace, but will realise that they will need to be at their best as Alan Pardew's side are also riding the crest of a wave at the moment.
Palace will travel to the Stadium of Light with the pressure off and will be confident of getting a result having beat Manchester City earlier in the week.
