Nuno Espírito Santo expressed frustration with the current handball law after his Wolves side lost 1-0 at Leicester.
Jamie Vardy converted a 15th-minute penalty after Max Kilman was adjudged to have committed an offence inside his own area.
Most neutral observers felt that Kilman was hard done by, though there was also general acceptance that referee Anthony Taylor was bound by the most recent interpretation of the law to point to the spot.
Speaking after the game, Nuno was wary of criticising the decision.
“The referee saw it, but I don’t know. This situation is very difficult to analyse,” the Portugal native said, per the official Wolves website.
“It’s not fair to say if it’s the right decision because VAR is not being consistent.”
Nuno admitted that the situation has left him at a loss on what to instruct his players to do.
“For us, it’s difficult, I didn’t see the images, but there’s no way to coach a player to defend without the natural movements of the arms,” he said.
“It is what it is and it’s difficult, but it can happen both ways. What we want is consistency in the decisions from VAR.
“It’s happening all over the Premier League, so what we expect from it in the future is to not have to talk about it.
“Anthony [Taylor] saw it, VAR saw it, for us as managers it’s very difficult to coach a player and tell him he can’t move his arms when defending.”
Wolves conceded a second penalty later in the first half, but goalkeeper Rui Patrício pulled off a fantastic save to deny Vardy another goal.
