Burnley boss Vincent Kompany was left frustrated after defeat to Bournemouth.
Kompany felt decisions didn't go their way for the 2-1 loss.
He said: "The story of this game can definitely lead to a lot of disappointment, anger even. You leave here with a very bitter feeling.
"I'm not even having a go at the officials on the pitch. I completely understand that you can make a mistake. It's the process that worried me. For us, there's a clear handball. It's a clear handball call, but there's no VAR check. We've just spent seven minutes checking to see if [Jay Rodriguez] is offside or not. It's probably the width of a hair.
"But the second one, the handball, I don't get it. The frustration is there at the moment.
"I've definitely brought it up [with the officials]. I think it was a respectful conversation. It's not something I can change now, but I've not been given answers."
On Rodriguez's disallowed goal, he added: "I could see them changing angles, drawing different lines. Sometimes the line turned up green, which means it's onside, and sometimes it turns out red, which means it's offside. It's sometimes like going to the casino and putting all your chips on a colour."
