Chelsea boss Thomas Tuchel felt his side had done enough to win the FA Cup but "decisive" video assistant referee calls went against them.
The Blues lost their second successive final as they were beaten 1-0 by Leicester courtesy of Youri Tielemans' stunning strike at Wembley.
There was suggestion of a handball by Ayoze Perez in the build up but a VAR review deemed no infringement.
"The players said straight away it was a handball," said Tuchel.
"So now for the second game in a row there was a handball against us, and VAR is not interfering.
"Against Arsenal there was one on the line, and again today, and they are very decisive.
"I'm not an expert in handball any more, I don't know when it's handball or not.
"I don't know any more when they need to punish it or it's OK to play with the hand."
