England's top flight will be the first league in world football to use technology to rule on disputed goals.
Referees receive a message on a watch within a second of the ball crossing the line to tell them if Hawk-Eye's cameras have verified that it's a goal.
But at a demonstration at Arsenal's Emirates Stadium, Wenger raised concerns about the process - for example when players are fouled before the ball crosses the line.
Referee Anthony Taylor told Wenger that a training day on Monday will be spent working through "anomalies like that."
