Former referee Keith Hackett believes officials should stop delaying raising their flag for offsides before someone gets injured.
Four goals were ruled out for offside in Chelsea's Carabao Cup final defeat to Liverpool on Sunday and at least half of them were instances where the assistant referee could have flagged for offside but waited for play to continue.
One of the goals that saw the assistant referee keep his flag down until the ball was in the back of the net was when Romelu Lukaku looked to have beat the offside trip and finished past Liverpool goalkeeper Caoimhin Kelleher.
