MOTD3: Full-backs, 3-5-2 and the best summer signings

Mark Chapman is joined by Danny Murphy and Phil Neville to discuss three key talking points from the opening weekend of the new Premier League season.

Subjects include the 3-5-2 formation used by new Manchester United boss Louis van Gaal, the role of the modern full-back, and the summer's best signings.

Van Gaal lost his first game in charge of United at Old Trafford, while champions Manchester City got their title defence under way with a win at Newcastle.
