Jamie Vardy gave the Foxes a first-half lead with a neat finish and just seconds after the restart, Stephy Mavididi capitalised on some poor defending to double the away side's advantage.

Mateta dragged Palace back into the match with his first goal moments later, but Leicester looked set to hang on despite being put under heavy pressure in the second half.

However, Conor Coady fouled Ismaila Sarr in the box and Mateta coolly dispatched his penalty kick to deny Steve Cooper a first league victory as Leicester manager.

Both sides are still searching for a first win after the four matches, with Leicester in 15th and Palace 16th in the table.

Cooper said after the match he wants the Premier League to provide clear evidence as to why Mateta's first goal was given.

The Frenchman's first goal was originally flagged as offside before it was overturned after a VAR review.

"I really want to see the image that says that was definitely onside because at the moment we have a few questions to ask of the Premier League," Cooper said. 

"There's definitely loads of good in the game, but if I'm being honest, it feels like a loss," Cooper added.

"Sometimes a point away from home ends up being really important, it might not feel like it at the moment, but it might be.

"We just needed to manage those moments after going 2-0 up, which we didn't quite do."

Palace boss Oliver Glasner was also disappointed to only pick up a point but praised the character of his side after coming back from two goals down.

"We are not happy with the point, but I'm really pleased and delighted with the spirit and the character of the players again," he said.

"With the great support from the stand, we had a very good belief today, and with a great impact also from our subs, and let's say all this together, keeping the belief, having a great support from the stand, and having a good impact from our subs. Then we came back. I think it's a compliment for the team for this comeback."

The Austrian was also pleased with his two debutants, Maxence Lacroix and Eddie Nketiah, with both featuring for the entirety of the match.

“Maxence was solid, and also we could see that it was his first competitive game for a very long time in some parts, but he was solid," Glasner said.

"Eddie showed what he showed during training, what we expected from him: he always can threaten the goals.

"He was a little bit unlucky with the two or three finishes he had, but he had good movements, and also before the very important penalty, he made this run and blocked the defender."
