Willy Boly's first-half header was disallowed after a video review ruled Pedro Neto was millimetres offside in the build up.

Hamza Choudhury was sent off for the Foxes after picking up a second yellow card for a reckless challenge on Leander Dendoncker with 14 minutes remaining.

But Wolves were left frustrated and only Sheffield United, with five, have had more goals ruled out by VAR decisions in the Premier League this term.

"There used to be an expression here in England about 'clear daylight' in these decisions," Nuno said.

"Something has to be done. When you have something and someone takes it away, you don't like it but the law is the law.

"I'm not a specialist on refereeing, we are not judging the work of the referees here. I'm frustrated with the situation and all that is involved. We should not be sitting here talking about this."

The point lifted Wolves to seventh in the Premier League, three points behind fifth-placed Sheffield United, with fifth now possibly offering a Champions League spot after Manchester City's two-year European ban for breaching Financial Fair Play regulations.

Clear chances were at a premium until late in the first half when Neto sliced wide after Kasper Schmeichel's poor pass and Raul Jimenez headed wide.

A minute before half-time Boly thought he had opened the scoring, glancing in Matt Doherty's header, only for VAR to rule Neto was marginally offside.

Choudhury walked after his second caution, for bringing down Leander Dendoncker, late in the second half and Wolves went for a winner.

Jimenez could have won it but headed wide in the final minute of normal time while Schmeichel thwarted Adama Traore's injury-time effort.

The point kept Leicester third but they have won one of their last five top-flight games with 17-goal top scorer Jamie Vardy having netted just once in his last 11 games.

"It was a good game considering it was 0-0," boss Brendan Rodgers said.

"The goal which was disallowed came for us a bit of sloppy play from us which led to the corner. Nuno will obviously be disappointed but when you're the manager on the other side of it it's brilliant.

"For us to keep a clean sheet and get through it in the end was very pleasing."
