Van Gaal needs to chalk out plans to fail Spain's tika-tika style of play, in which they excel like no other. Their ball possessing game has been catching the eyes of football fans all over the world and the same style of play has brought laurels to the country, so one can expect the same style when Spain play Netherlands. They would never trade their style of play for anything else.
What makes Spain a huge threat is the chemistry enjoyed between their team mates, as most of the players ply their trade in Spain itself and are primarily players from Barcelona.
Though, Spain may look favourite, one cannot discount Netherlands and their chances for lifting the 2014 FIFA World Cup. They do not have any dearth of quality in their squad as well. In fact, Netherlands must be a confident outfit, for they were one of the first teams from Europe to qualify for the mega tournament.
Players such as Robben, Van Persie, Sneijder, are players who could play an important role, if they are to progress in the competition. These mentioned players have been playing together for years, which only makes their understanding better. The trio could well be playing their last world cup and how badly would they be dreaming of finishing the world cup on a high. But, in order to acquire their dream, it is not only these players but the entire squad, which needs to play as a unit.
