Scotland travel to group leaders Belgium needing to win to get a struggling campaign back on track.
“I trust that we have the quality to win this game, but I do not think it will be easy”, the former Ajax star told Belgian broadcaster RTBF.
“The Scots always give 100% for their country. Following their poor start in Group A, they come to Brussels to win points.
“We cannot underestimate them. Many of their players play in the Premier League and they have an experienced team.”
