Tottenham head coach Ange Postecoglou has questioned the use of new VAR protocols in the EFL Cup semi-finals, which are taking place this week.

Unlike in the Premier League, referees will explain VAR decisions to the crowd through an in-stadium microphone, which will sync up with the PA system.

The measure is a trial and is limited to when the referee has checked the pitchside monitor and overturned a decision. It will also only concern decisions made on offside and accidental handball by a goalscorer.

While Arsenal boss Mikel Arteta was supportive of the measure, suggesting it brings added clarity, Postecoglou was of the opposite opinion.

"Do I welcome it? No," he said on Tuesday.

"Do you think if they had shown the handball on the weekend that our supporters would have been happy?

"Would they have come away and said, 'oh, that's great, they explained it?'"

Spurs lost 2-1 at home to Newcastle on Saturday, with the visitors' equalising goal being given despite the ball striking the arm of Joelinton in the build-up.

The defeat left them 12th in the Premier League table, 10 points off the top six and eight above the relegation zone ahead of their EFL Cup semi-final first leg against Liverpool.

"But at the same time, I have to accept that it's coming in. I have to accept that this is the way forward. I have to accept that I have to be a part of that," Postecoglou added.

"But it shouldn't surprise anyone if I'm not a sort of cheerleader for those kinds of things."

Next up for Tottenham after they host Liverpool is a trip to Tamworth in the FA Cup third round on Sunday.
