Venus said: "I think for both of us, what's so unique about the situation is that we're both very good players.

"We both know when we walk out there, it's not like you're guaranteed a win. I think that's what makes it challenging for both of us."

Serena still leads 14-11 in the head-to-head with her sister, who she played for the first time on the professional circuit 16 years ago,

Ahead of the final, Radwanska, who has won her last two matches against Venus, said: "She's definitely on fire. Definitely she's playing amazing tennis this week.

"She beat a lot of good players on the way to the final, especially Serena. It's not going to be the easy one."

The win in Canada will be a boost to Venus, 34, in her build-up to the final Grand Slam of the year, the US Open, which starts at Flushing Meadows on 25 August.
