If Spain score first, there's no way they'll concede.
Robben offers nothing defensively which Brazil took advantage of when Robinho made an unmarked run for the goal. Sneijder also does very little defensive work. Kuyt offers good defensive discipline on the wide left but Iniesta likes to drift inside and becomes another central player, this will test Kuyt to his absolute limits. When Iniesta drifts inside, Spain outnumber the Dutch in the centre. It'll be interesting if they sit back or if they pressure the Spanish midfield. Van Bronchorst has tightly marked his opposition to make up for his lack of pace, but Iniesta is not a genuine wide player. Spain will pressure the Dutch, which could give Sneijder space between the lines which is incredibly dangerous for a player of his calibre. But if Spain score first, they can play their tika-taka football for as long as they like.
