Silva and his players are furious with the VAR calls that were made today as the Blues won 2-0.
He said afterwards, "(VAR) changed the game. Overall performance wise we were outstanding first half, playing the game like it should be played. We should be proud. We were clearly the best team in the first half.
"It is a great finish from our young boy (Josh King). The referee and VAR decision I cannot control. I try to speak as best as I can. I have some words, everyone is shocked in the dressing room, people watching TV, everyone.
"Many things happen. The first goal when they give eight minutes extra time. Nothing happens in that eight minutes. Chelsea have a corner, then another corner. It is already nine minutes. The game should be stopped. I would like to understand why.
"The penalty is another shocking decision. Someone at the screen (VAR) has seen something unbelievable like a stamp (for the disallowed goal). The same people did not see a foul on Josh King and handball by Joao Pedro, and the stamp on Alex Iwobi. The same four eyes saw something unbelievable in the first half didn't see the same for us in the second half.
"The has to be balance. The official was very balanced because after the decisions our emotions were too much. He understood in the right moments, did not show yellow cards and I have to praise him.
"He refereed the game like a derby. He didn't see something (for Josh King's goal) and by the protocol he should be called to the screen if it is obvious and clear but no-one can tell me that it was."
