Wales v Namibia
Wales' performance against Samoa was nervy and they looked like a side who had to win but, importantly, they did.
Samoa have been a bit of a nemesis for Wales in the past and this was a tricky encounter. To beat them was a great effort and I though the physicality shown by Wales was tremendous; they really took Samoa on up front and at the breakdown area.
Wales lost the presence of Dan Lydiate early on which was a blow but I thought Luke Charteris and Sam Warburton were outstanding. Wales will be hoping that Lydiate is back for the knock out stages, though.
Wales also lost James Hook but I thought Rhys Priestland did particularly well and led Wales through a very physical game.
I don't think Wales should make massive changes for Namibia, but I think we will see the likes of Ryan Jones and Stephen Jones back into the team.
I think Gethin Jenkins needs some more game time to get him fitter for the knock out stages, and Lee Byrne possibly needs a run, too. Wales should be looking at five or six changes but no more than that.

Scotland to beat Argentina - 11/8; Scotland to win by 1-5 points - 5/1. Bet now
If Stephen Jones comes back in, that gives Priestland a much-needed break after two very physical games. I would also like to see Leigh Halfpenny start either at fullback or on the wing. He looked really sharp coming back from injury and could be a real weapon.
I think Gethin Jenkins needs some more game time to get him fitter for the knockout stages, and Lee Byrne possibly needs a run, too. Wales should be looking at five or six changes but no more than that.
This is a big game for Wales. They are still third in the pool and the Fiji v Samoa game is going to be a very tough encounter. If Samoa win that then that sets up next Friday for a massive game between them and South Africa.
It could very well come down to bonus points and that is why Wales have to be very sharp against Namibia. A good win is not only vital for the bonus points, but also for morale. I expect them to win by a large margin and would look at the odds for Wales opening their account with a try. It could offer a good return.
Scotland v Argentina
Scotland (11/8 with Sky Bet) have a very tough game against Argentina which I think will decide their fate for the quarter-finals. Before the tournament started, I thought that Argentina were over the hill but they have shown that there is still plenty of fight left in them.
At this stage, it is probably a more important game for Argentina - if they lose then they are definitely out. If Scotland lose emphatically, they will have one more go when they take on England. However that does not mean that Scotland won't be 100 per cent committed for this game.
Will the pressure be too much for Argentina? I just have this feeling that Scotland will pip them to the post. Scotland have not got into their stride and Argentina will make it very hard for them, but I just feel that Scotland will be five points better than Argentina this weekend - 5/1 with Sky Bet.
