Neil Jenkins said yesterday that the intensity of this season’s Six Nations Championship will contribute to “a good few headaches” in selection for British and Irish Lions boss Warren Gatland.

Two thirds of the games so far have been decided by six points or less, with only Italy finding themselves way off the pace.

And with some huge contests still to come, potentially highlighted by England’s trip to Dublin next month, Gatland’s player selection pool could further expand as he builds towards the New Zealand tour squad announcement on April 19.
