The flamboyant trainer was pleased with Oranje's victory, and feels that he did not take any unnecessary risks despite fielding an experimental line-up
The Dutch struggled to contain the Turks after grabbing an early lead via Robin van Persie, but they eventually bagged the full three points as Luciano Narsingh put the match to bed well into stoppage time of the second half.
"It was squeaky bum time until we netted that second goal. Turkey are a great team with some very good players, yet we beat them. This is a very important victory," Van Gaal stated to SBS6.
The former Bayern Munich coach opted to field a rather inexperienced team as he left out several regulars - including Klaas-Jan Huntelaar, Nigel De Jong, Rafael van der Vaart and Ibrahim Afellay - but Van Gaal does not feel that he took too much of a risk by fielding a number of promising youngsters.
"I do not think that I did anything crazy, but I did expect more from our defence. Bruno Martins Indi and Jetro Willems bounced back after the interval, though. That was rather impressive.
"We created a lot more chances than Turkey and should have decided the match at an earlier stage. That is something we will have to improve on."
Oranje resume match action on Tuesday when they take on Hungary.
