The Netherlands has flown from its training base in Rio to Salvador with an apparently fully-fit squad, giving Louis van Gaal a dilemma about who to play in midfield.

Jonathan de Guzman appears to have fully recovered from a hamstring strain and to be fit enough to play in the Netherlands' crucial Group B opener against defending champion Spain on Friday.

Earlier this week, Van Gaal looked to have settled on Feyenoord's Jordy Clasie as one of his three midfielders alongside Nigel de Jong and playmaker Wesley Sneijder.

Now the Netherlands coach has to make a choice.

The midfield berth looked to be the only undecided position in Van Gaal's team as it flew out of Rio ahead of a closed training session Wednesday evening in Salvador.
