Murchie demands major improvement in Wales defence

Defence coach Peter Murchie has called for a vast improvement in his area of the game when Wales resume their Nations Championship campaign on Saturday against Japan (16:40 GMT).

Murchie is preparing for his second campaign in charge of the defence after joining Steve Tandy's backroom staff from Japan side Kobelco Kobe Steelers.

In July, Wales defeated Fiji in Cardiff but lost to Argentina and South Africa, with the side missing more than 100 tackles and conceding 15 tries during the three games.

Murchie is expecting a lot more from the Welsh squad during the next month.

"From my side in the summer, we can be much better," said Murchie.
