The game against Wales at Murrayfield is going to be a real challenge for Scotland.
The Welsh have had a terrific RBS 6 Nations so far and their game against France in Paris was magnificent.
To come through for such a great victory showed real character, so I think its going to be very, very tough for Scotland.
The great hope for Scotland is that, no matter what anyone says, the Welsh will have one eye on their next game against Ireland, and there is a chance that they could underestimate Scotland.
The Welsh have some fantastic runners with the ball in hand, and its been wonderful to see rugby played in the fashion that theyve played it.
The thing to remember, though, is that its not just been in this years RBS 6 Nations tournament that the Welsh have been playing this kind of rugby.
Going back to the 2003 World Cup, they were magnificent in the game against New Zealand and then in the quarter-final against England. The New Zealand game in particular was unbelievable.
Overall I think Matt Williams will be very disappointed with position that Scotland find themselves in at this stage of the tournament.
They had the chance to beat France in Paris, and had they done that their tournament could have turned out very different.
At least Matt Williams will be happy to have broken his duck under his command against Italy but Scotland will have to improve significantly against Wales if they are to have a chance.
