Chelsea manager Antonio Conte and his Arsenal counterpart Arsene Wenger have questioned aspects of the VAR system after it was used during their goalless League Cup draw on Wednesday.
The system reviewed two penalty decisions, one for each side, during the first leg of the semi-final clash with match referee Martin Atkinson and VAR assistant Neil Swarbrick agreeing that neither incident warranted a spot-kick.
Conte said he was 'positive' of the new technology but was frustrated with the insufficient stoppage time at the end of the second half to accommodate for delays caused by VAR and injuries.
