Leicester manager Steve Cooper says the club have met with the Premier League to discuss "an awful human error" which gave Crystal Palace a goal in last weekend's 2-2 draw.
Cooper's side took a 2-0 lead early in the second half at Selhurst Park courtesy of Stephy Mavididi but Jean-Philippe Mateta scored twice to give the Eagles a point.
Mateta's first goal was originally ruled out for offside, with the video assistant referee (VAR) overturning the decision despite replays appearing to show the French striker in an offside position.
Cooper says the club have shown evidence to the Premier League but have not received an apology.
