Here is the Wales team
Wales v Argentina: Leigh Halfpenny (Cardiff Blues); Alex Cuthbert (Blues), Scott Williams (Scarlets), Jamie Roberts (Blues), George North (Scarlets); Rhys Priestland (Scarlets), Tavis Knoyle (Scarlets); Gethin Jenkins (Toulon), Matthew Rees (Scarlets), Aaron Jarvis (Ospreys), Alun Wyn Jones (Ospreys), Ian Evans (Ospreys), Josh Turnbull (Scarlets), Toby Faletau (Newport Gwent Dragons), Sam Warburton (Blues, capt).
Replacements: Richard Hibbard (Ospreys), Ryan Bevington (Ospreys), Paul James (Bath), Robin McCusker (Scarlets), Justin Tipuric (Ospreys), Mike Phillips (Bayonne), James Hook (Perpignan), Liam Williams (Scarlets).
I'm not too happy with this tbh.
Priestland has been playing poorly all season and also wasn't great in June against Australia. On form he shouldn't be in the 23 never mind starting.
Turnbull I'm not sure about, I think this is a missed opportunity to see Tipuric and Warburton play together, I also would have chosen Shingler ahead of Turnbull to play 6 as well. McCusker on the bench is also bad, he offers no impact and has been giving away silly penalties of late, he is seen as a very versatile back rower who can play all over the back row but imo he is a 6 and only a 6.
Big shame Ashley Beck doesn't make the 23. Hibbard also probably deserved to start on form, but I'm not too bothered as long as Matthew Rees throws in straightly.
Surprised Phillips is dropped, will be interesting to see how Knoyle goes.
