You don't want to see that sort of behavior on the pitch, we all understand that this is a sport of contact, there's a very big difference when you are wrestling with a player and stopping a player trying to score a goal, so I think now we have got a real help toward a referee and that sort of behavior in the box is gonna be punished. You need to be a little bit more clever with your marking, be very careful with a contact. Now you gonna be checked in every single marking situation in the box. I think that's a real advantage of VAR, " Martinez told journalists.
