Newcastle take on Wolves again at St James’s Park tonight, this time in the EFL Cup.
The match is followed by a Championship fixture away to Aston Villa.
“The cup game, we have to use it to get back the confidence and to get the fans back behind us again too,” said Diame.
“We need to win this game and then after that get ready for the next league game.
“It will be a battle (against Villa). We treat every single game like that and stay focused on our job.
“Even though we got a very good result against QPR, we need to stay very focused and this was a disappointing result against Wolves, but we will be fine.”
