Wales flat despite win - Gatland

Wales coach Warren Gatland reveals his players are "a bit flat" in the dressing room and disappointed with their own performance despite beating Italy 24-3 at the Millennium Stadium in Cardiff to take their fourth straight win in this year's Six Nations.

The New Zealander says his side were "frustrated" that the game turned into a "dog fight", but is relieved that Wales are still on target for a "special" third Grand Slam in eight years.
