Russell, 33, produced an excellent show as Scotland swept apart England 31-20 within the Calcutta Cup at Murrayfield final weekend and shall be looking for to inflict extra Six Nations injury on winless Wales.
Tandy shall be hoping that doesn’t occur on the Principality Stadium on Saturday.
“We’ve got to trust ourselves in what we’re trying to build,” mentioned 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 could have moments within the recreation and we’re conscious of what Finn and the remainder 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.”
