The former French international coach offered his thoughts on the four FIFA World Cup quarterfinal matches to be played over the weekend.

"I expect a lot of emotion because they are two tournament teams that are regularly through to the quarterfinals or semi finals they have met a couple of times in the final," said Houllier of the Germany-Argentina blockbuster.

Houllier, who formed part of FIFA's Technical Committee during the 2002 and 2006 World Cups, said Paraguay will be a difficult challenge for Spain. "The Paraguayan team is very difficult to score a goal against because they have a very strong defence."

As for Uruguay verses Ghana, Houllier would like to see the first African nation qualify for the semi-finals but thinks the South American team is growing in confidence. Brazil against the Netherlands is sure to be an interesting encounter according to Houllier. The Frenchman describes Brazils as looking "extremely confident and solid," and the Netherlands as "well organised".
