Tottenham boss Mauricio Pochettino feels controversy around refereeing decisions is hurting the game.
Tottenham were awarded two penalties including one in the 95th minute of their draw at Liverpool, while midfielder Dele Alli was booked for simulation.
Liverpool boss Jurgen Klopp fumed at the penalty decisions while Pochettino was much more positive about referee Jon Moss and his assistants.
"Now we are so focused on minimal details. I am worried. It's a sport that we love, a passionate sport that people love to watch around the world," the Argentine said.
"We will be pushing that sport into a very rigid structure with VAR, with being focused too much on the small actions like this."
Tottenham host north London rivals Arsenal in a Premier League match at Wembley on Saturday.
