Huge game this weekend in the Barclays Premier League, as the past greats of English football, Manchester United, take on the champions-elect, Chelsea. Ian Fiveankles explains EXACTLY what happens in this match, so you don't even have to watch it. A meeting with Manchester United is always a grand occasion yet Chelsea's visit to Old Trafford on Sunday has an extra degree of grandeur due to the men at the helm of their respective clubs. Jose Mourinho may well be master of all he surveys in the football world though he owes much of what he has become to the tutelage of Louis van Gaal.
