RORY Best believes Andy Farrell should stick with the players who he knows will make his World Cup squad.
But the ex-Ireland skipper says that while it is important to maintain the momentum that put them back on top in the world rankings, the team's dependency on Johnny Sexton and Tadhg Furlong should be addressed during this Six Nations.
Whatever about the championship, Best feels that Farrell, who names his Six Nations squad this morning, must not experiment during the World Cup build-up.
