The game will give Sir Clive Woodward some much-sought after time with the players in advance of the tour. Woodward has been pressing for time with the players during the season and this will be seen as a coup for him, as the Lions break with the norm in hosting a domestic match, though they did host a Rest of the World XV in 1986 as part of the IRB centenary celebrations.
The Irish contingent can be forgiven for thinking to themselves "Could you not find anybody else, lads?", as Argentina and Ireland have met so often recently. And in matches that have been nothing if not physical. Add in the forthcoming Autumn international and Irish members of the Lions party may be meeting the Pumas for the seventh time in less than six years.
For the Pumas, it's a terrific opportunity to go after the scalp of the cream of the talent from these islands.
It's also a great coup for the Welsh Rugby Union, as they have fought off the attentions of Twickenham in landing the fixture. It will provide a significant cash injection to the WRU.
