Wales captain Dewi Lake insists defensive improvements will be evident when they face Scotland in Cardiff on Saturday in round three of the Six Nations.

Scotland captain Sione Tuipulotu on Friday paid tribute to Wales coach Steve Tandy for turning him into Test-match leadership material.

Finn Russell is aware of tough Welsh challenge for Scotland but he is keen to avoid any complacency for their Six Nations ambitions.

Blair Kinghorn and Duhan van der Merwe are "war ready" to take on Wales as they prepare for their first outing in this Six Nations, according to Scotland captain Sione Tuipulotu. The British and Irish Lions backs were left out for the round one defeat by Italy - and last weekend's stunning victory over England.

Every match of the tournament will be shown live across BBC and ITV platforms. Wales v Scotland will be live streamed on BBC iPlayer for free. Fans can tune in to watch all the action live and on the move via a range of device, including smartphones and tablets via the ITVX app.
