Roy fears the use of VAR technology
Roy Hodgson fears the introduction of Video Assistant Referee (VAR) technology in English football could spark chaos.
VAR will be used for the first time in a competitive club match in England on Monday when Brighton host Crystal Palace in the third round of the FA Cup.
The former England manager, who has overseen Palace's remarkable improvement from near-certainties for relegation to contenders for a mid-table finish, was present at the 2017 Confederations Cup in Russia when VAR was used.
He was unimpressed by its influence, and while he believes if implemented correctly it can prove a positive addition in officiating matches, is concerned about the impact it will first have.
"I experienced it during the Confederations Cup, albeit from a television studio," said the 70-year-old. "It was chaotic there, so if you ask me what my opinion of it is, based on my experience of what happened during the Confederations Cup, it didn't work very well at all, because the communication between the referee and the guy on the machine wasn't working well.
"No one wanted goal-line technology and now we can't live without it so I am certainly not one of those people who would suggest there's no future for technology in the game. But the way our game is, and the fluidity of the game, and the way spectators expect the game to continue...
"Every time a player goes down injured, the fans get very frustrated when one player gets treated, be it their own player or an opponent player. So there are a lot of questions to be answered with regard to how things can dovetail together, but if they can get it to dovetail together, and it stops gross injustices, then on our side of the fence we'd be all for it."
