Everton's David Moyes unclear on assistant referee plans

In addition to two running the line, one will be stationed behind each goal to rule on decisions inside the penalty area.Moyes admits he remains unclear over the scope of the extra assistants' responsibilities, revealing he has received nothing more than "a sheet of paper" detailing where they will stand. "We think we should have had a clear briefing," he said before his side's meeting with AEK Athens. "The clubs involved should have had it set up in a practice match or at least had someone come to explain it to the players, but we think they're not entirely sure how it's going to work."I think you'll find more penalties and infringements for things like jersey-pulling and blocking, but I could name 20 things I'm not sure about."
