“On a personal level, it’s great just to be picked to start again,” said Jackson. “It’s a good vote of confidence.

“Myself and (fellow fly-half) Duncan (Weir) understood Sean’s intentions at the start of the season to let us both have game-time and to develop, but of course you want to play and you want to start, and especially when it comes to the Heineken Cup.

“It was good to get out together and just spend a little time talking about the competition in a social way really rather than in an analysis room, which we've done plenty of as well.

“The guys spoke about the big wins they have had, such as Toulouse out there, Gloucester last season here, Biarritz and Bourgoin so I’m looking forward to playing.”
