Maradona's tactics will come under scrutiny

Argentina's Lionel Messi heads into the World Cup as the player everyone wants to see but it will be the strengths and weaknesses of coach Diego Maradona that will determine how far the South Americans progress.

Argentina are clear favourites to top Group B ahead of Nigeria, Greece and South Korea but the critics will be looking closely during their opening games to see if Maradona, an inexperienced coach, has finally got the balance right.

He was often at the centre of controversy in the World Cup as a player - his 'Hand of God' goal in the 1986 finals, which Argentina went on to win, and expulsion at the 1994 tournament due to a failed doping test ensured he hogged the headlines.

But this time it his decision making that is under scrutiny and he certainly has not played safe -leaving out experienced Inter Milan pair Javier Zanetti and Esteban Cambiasso.
