Newcastle boss Matthias Jaissle says his side must "avoid individual mistakes" if they are to return to winning ways against Everton on Monday night.

The Magpies failed to capitalise on Sunday's win over Crystal Palace when they lost to the Toffees 3-1 at Hill Dickinson Stadium on Thursday night in the Carabao Cup.

It means Jaissle's side have won just two of their last six matches in all competitions, but they have the opportunity to exact instant revenge for their most recent defeat on Monday.

"First of all it is something where we need to work on, that we are not conceding so many goals," Jaissle said.

"We need to just avoid these individual mistakes especially where the opposition is not that dominant on the pitch. We need to improve for the next match on Monday."

Newcastle have conceded 13 goals in their last six games in all competitions, and Everton's opener on Thursday came from another mistake in Amar Dedic's poor clearance.

"It is something what I mentioned about being mature and more clinical and not giving almost a gift for the opposition to score, it feels the opposition is not giving us these gifts," explained Jaissle.

The Magpies' misfiring attack may also take another blow, with striker Will Osula a doubt after a crunching tackle from James Tarkowski appeared to leave him in discomfort.

"He twisted his ankle when he took the shot," Jaissle added.

"Right now, it's too early to say whether he will be fit for Monday.

"When it comes to scoring goals, we need to be more efficient out of so many occasions. How often we enter the box of Everton, there needs to be more than only one goal."
