Sunderland star Sebastian Larsson believes that silly mistakes are the reason behind the club's poor form this season.
The Swedish international feels that the team have been over-complicating things and, as a result, they have been making far too many errors in their matches
Sunderland reverted to a back-to-basics style against Crystal Palace to great success in midweek, picking up a 3-1 win, and Larsson now feels that this is the approach they need to take going forwards.
“I think that our problem lately has been giving silly goals away,” Larsson explained to the club's official site. “You can’t do that at this level so we spoke about it last week and went back to basics.
“We were back to being solid again against Palace and we will have to do the same again on Sunday, because you can’t give anything away especially against a team like Everton.”
The triumph over Palace was only their second win of the campaign and it means they are now away from the relegation zone.
The Black Cats had fallen into trouble after a series of disastrous results, where their error-prone streak was on display.
The 8-0 defeat to Southampton may have been the best example of this, but their defensive deficiencies were also on display against Arsenal.
It is a trait that they must stop and they will be looking to add three further points to their tally when they take on Everton.
Doing so will be easier said than done because of the Toffees form has been good of late, with Roberto Martinez's side avoiding defeat in their last five games in all competitions.
It is a run that has highlighted the quality that the Merseyside outfit have at their disposal this season, and Larsson and his teammates will have to be at their very best to stop them extending it.
