Queens Park Rangers are in action again on Tuesday evening.
Rangers were beaten 3-2 by Middlesbrough last Friday, and their performance in the contest fell short of their recent standards.
As a result, the Dutch boss has suggested that he could make a number of alternations to his starting line-up at Elland Road on Tuesday evening.
“We need to go there with a lot of positivity and try and to get our football the same ways as Boro, but get three points this time,” he said.
“I will freshen the side up, because it will be another energetic game.”
Rangers have been in good form of late, but their defeat against Boro was a disappointment and ended any slim hopes they still had of making the play offs.
QPR are meeting Leeds at a good time, as Steve Evans’ side have been badly off form of late.
The Yorkshire side lost their last home match 4-1 against Huddersfield Town, and they were beaten 2-1 by Rotherham United in their most recent outing.
Leeds will also have the added complication of having debutant goalkeeper Bailey Peacock-Farrell in between in sticks on Tuesday evening after usual first choice, Marco Silvestri, picked up a red card against the Millers.
