Burnley welcome Crystal Palace to Turf Moor in the Premier League on Sunday afternoon, and are favourites to pick up all three points given the contrasting form of the two sides this season.
It has been reported that former England manager Roy Hodgson could be under consideration to take over from De Boer should results not improve this weekend. "I can not believe we lost", said De Boer. "When I'm still the manager of Palace I will give 100 per cent", he said.
When the summer transfer window closed Crystal Palace had secured just one major signing, Liverpool's Mamadou Sakho, a player who, whilst on loan at Selhurst Park, had played a significant role in their Premier League survival fight last season.
A horrific back pass from Lee Chung-Yong gifted Chris Wood the only goal of the game early on in the first half.
"We have to make sure we are right and I think we will be".
De Boer accepts that the disappointing display against Swansea in their previous game revealed that the players are still adapting to the possession-led style he wants them to play.

As if that was not enough, Mikel Obi , with a corner kick taken by Victor Moses , slipped in the second goal at the 41 minute. Ghana , who have been to the last three World Cups, are way off the pace in Group E after being held at home by Congo .
When Sam Allardyce was around, they were getting pelters for the way they played, but at the end of the day some teams can only play a certain way and this squad clearly may not be able to and he may have to play a certain way. Its best chance fell in the 89th minute to Scott Dann, who glanced a header wide from inside the six-yard box. "We are four games in, it's a awful start but we have to stick together".
"But if you look all over at how we showed spirit, I think we were quite dynamic".
'I can not believe we lost, there is still frustration about the result but not about our performance, ' he said after watching Scott Dann miss a golden chance to equalise in the 88th minute.
"There was a very positive vibe in the team, so I am very positive for the future".
"Everybody knows you can not expect us to win every game".
"I thought they were the better side", he said.
Thats what any footballer dreams about, its the biggest league in the world, he said.
