Wales wing George North has called on his teammates to reproduce last season's form if they are to defend their Six Nations crown.

Wales are currently on a seven-Test losing streak, but the Ospreys wing remains hopeful that they can improve ahead of their opener against Ireland on February 2.

"With the Six Nations... we got last year's Grand Slam so hopefully we can push on from that and carry that forward," North told BBC Sport.

"We've had our dip in form now, we know we were doing a lot of things wrong and certain things right, and we'll work on that now."

The 20-year-old has made 26 appearances for his country.
