The pair were today named in the Oranje squad for the Wembley clash alongside rookies Ola John and Luciano Narsingh, and will be hoping to impress for the national team after difficult spells at domestic level.
Robben has recently been left out of the Bayern Munich side, while Sneijder has been a part of an Inter Milan line-up which has gone seven games without a win in all competitions.
Van Marwijk remains confident, however, that two proven performers will shine if called upon. "Fortunately form is something that comes back," he said.
"Maybe Arjen wants to be happy and that also goes for Wesley. They should get back to basics, that will be for the best."
Van Marwijk named a balanced squad, with the experience of Sneijder and Robben complemented by the youthful exuberance of John and Narsingh.
"Both boys are developing rapidly," he added. "They have proved they can play under pressure and find that good final pass."
John was delighted he had been offered the chance to link-up with the senior squad. "It's a nice surprise," he said on the FC Twente website.
"At the beginning of this season, I never thought I would be called up to the Oranje squad when I was just a reserve. You get to train with world-class players and I want to learn as much as possible. The selection is a reward for my performances this season."
Former England manager Steve McClaren, now John's manager at Twente, added: "Ola deserves to go to Wembley, he is a lucky boy. This selection is a nice reward for his performances this season - a personal success and also one for the club."
