Six Nations: Welsh players 'flat' despite win over Italy

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.
