West Ham United boss Slaven Bilic has advocated the use of video technology in football.

The Croatian believes that the technology to closely look at controversial calls will help the smaller clubs in getting fair treatment from the referees.

"The big clubs are always getting decisions," he said. "I don't think it is deliberate. But it is the same in Croatia, Spain, Germany and Turkey.

"The biggest clubs also have the biggest press. If they are not given a penalty it is a big scandal but if a small club is not given one it is shown at midnight and not prime time. That's why they are big clubs.

"I don't understand the managers when they say: 'I will not comment about the referee'. Why? How can I not comment about something that influences everything? It has a major impact so at least after the game I want to say my opinion in a nice and polite way.

"It is impossible for referees to do everything right with the speed and movement so it is better to slow the game down for three seconds."
