Russell, 33, produced an outstanding display as Scotland swept aside England 31-20 in the Calcutta Cup at Murrayfield last weekend and will be seeking to inflict more Six Nations damage on winless Wales.
Tandy will be hoping that does not happen at the Principality Stadium on Saturday.
“We’ve got to trust ourselves in what we’re trying to build,” said Tandy.
“We need to be making sure we stay connected around the defence and are not giving him easy options or getting too narrow because he will find the soft spot.
“He will have moments in the game and we are aware of what Finn and the rest of the Scottish backline can do. It is a British and Irish Lions backline.
“We’ve got to make sure we are focusing on where we can be better than last week to implement more of our game.”
