Sportsmail's Jamie Redknapp delivers his verdict on a weekend of shocks in the Premier League. First, Liverpool were humbled at Upton Park, losing 3-1 to West Ham to make it three defeats in five this season. And on Sunday, Manchester United were soundly beaten by Leicester City 5-3 giving Louis van Gaal much to ponder. There was also the small matter of a Frank Lampard goal against Chelsea for Manchester City in a 1-1 draw. How Van Gaal has to prove his genius It doesn’t take a great tactical mind to go out and sign Radamel Falcao and Angel di Maria. Any United fan could have done that. It’s not rocket science. But fixing the United defence is another matter. Now we really will find out if Louis van Gaal is a genius.
