Wilder last week accused Klopp of being “selfish" over his demands for the return of five substitutes because it would help Liverpool.
And Wilder has taken aim again at the Reds boss for not calling for supporters to be allowed back into all Premier League grounds.
“He's a world-class manager and a world-class politician, who cares about Liverpool," he said. “That's all he cares about.
“He was never going to say what about Sheffield United getting their fans back in or Newcastle or Man City or Man United or anybody else. He's a world-class politician.
“I know his background on support and how much Anfield has been a fortress. The Liverpool support is magnificent, I know it is because my old man is from that part of the world.
“I know he's been vocal on that and Jurgen isn't going to say it's not right that they can have fans in as they're in tier 2 and Sheffield United, Leeds, Manchester and all the rest of the north are not allowed in.
“It was funny looking at that map, wasn't it? Shock! I think us in the north were fully expecting us to be in the old tier three as they kindly put us in."
