Holland coach Bert van Marwijk will treat Arjen Robben with caution ahead of Monday's last-16 clash with Slovakia after the winger made his first appearance in the World Cup.
Bayern Munich's Robben had been sidelined with a hamstring problem but came on as a substitute in Cape Town on Thursday night and hit the post to set up Klaas Jan Huntelaar's winner in his side's 2-1 win over Cameroon in their Group E dead rubber.
Van Marwijk said: "The idea is to build him up slowly and gradually. I'm really pleased he was able to play for 20 minutes and nothing happened, he didn't get injured. But there are three more training sessions and he will be growing step-by-step."
He added: "I take it he'll be able to play in the next match but I don't know if he will be part of the first XI."
Holland made it three wins from as many Group E matches with victory over Cameroon.
With the Oranje already through to the last 16 and Cameroon out, it took Robin van Persie's 36th-minute flash of inspiration to get things going at Green Point Stadium.
Samuel Eto'o's second-half penalty levelled matters until substitute Huntelaar's 83rd-minute winner continued the group winners' momentum heading into a last-16 clash with Slovakia.
After the game Cameroon coach Paul Le Guen confirmed he will leave his post when his contract runs out this summer.
"My contract was coming up and it's the end of this mission," said the Frenchman.
"It was planned to be this way. I'm going to think about the future now, and we'll see."
