Beating Leinster a tough ask - Kiss

Ulster director of rugby Les Kiss says his team face a huge challenge to overcome derby rivals Leinster at the RDS on New Year's Eve.

Ulster are likely to rest Ireland trio Rory Best, Paddy Jackson and Iain Henderson but Andrew Trimble should start along with Tommy Bowe.

Leinster are five points clear of fourth-placed Ulster going into the Dublin encounter.
