Explained: Why VAR could not recommend Mateo Kovacic was sent off for second reckless challenge against Arsenal

The midfielder was booked for a reckless tackle on Martin Odegaard and the challenge was soon reviewed by VAR for a possible red card, but referee Michael Oliver's decision stood.

Just six minutes later, Kovacic caught Declan Rice with a late tackle that brought the England international down and although Oliver whistled for a free-kick, he waved away Arsenal's calls for a second booking.

The Gunners clearly felt that Kovacic should have been given his marching orders for the second foul at least and although VAR intervened to review his earlier tackle, there was no check on the tackle on Rice.

The reason VAR was not involved to decide whether or not Kovacic should have been given a second yellow card is that the video assistant can only draw the referee's attention to a possible red card. The VAR is not permitted to interrupt for decisions regarding a possible second yellow card.

City will hope to go on to take all three points before the international break. They are next in action on October 21 against Brighton.
