Everton manager Sean Dyche was left frustrated after his side failed to convert chances into goals during their 1-0 defeat to Fulham.
Everton may have created twice as many chances as the visitors, though they were undone by a late goal as two Cottagers substitutes Aleksandar Mitrovic and Andreas Pereira combined to provide the third, Bobby Decordova-Reid, with a tap-in.
Nevertheless, it was the chalking off of Keane's goal which proved the most controversial moment.
The Everton man turned the ball into an empty net after goalkeeper Bernd Leno had dropped it in a challenge with James Tarkowski.
"Very frustrated with the outcome. We played well and a lot of the things we are looking for were there, especially first half," said Dyche.
"We limited them to almost no chances or nothing clear while creating nine or 10 in the first half, five of which are high quality. We had one of the highest chance counts in my time. So the mix of the performance is right, but we have to score a goal.
"I am a big fan of VAR, I don't know why (Keane's goal was not referred) on this occasion, I get the idea they are promoting the idea the referee's decision is first but they should step in on this one.
"I can't really work it out. I have seen it back, Tarky does nothing really, minimal contact other than the keeper landing on him.
"The minimum should be that you go and look at the monitor. He didn't do anything to put the keeper off and he drops it."
