The Belgians will take a big step towards the second round of the tournament if they come away with the points in Rio de Janeiro.
However, Wilmots is expecting Fabio Capello's Russia to provide organised opposition tomorrow evening.
"It could be a very tactical match, Capello has a great track record at some great clubs and we will see what his approach is on the pitch," he is quoted as saying by ITV Sport.
"We saw Russia play Korea in quite a rigid formation but we will wait to see against us. The most important thing for us is we have to shut down space."
