Two victories over the capital club either side of Christmas propelled us on a seven-game winning streak and gave us renewed belief that, if we stayed true to the style of rugby we were trying to play and executed our game plan, we could very much be a match for any side.

There have been some big victories in this run, none more so than our win at Scotstoun over Ulster, while seeing off Northampton in the Heineken Cup was another huge boost.

However, nothing has been achieved and, although we have put ourselves in a very strong position to claim our first home semi-final in the play-offs, we still have it all to do.

When we return after our one-week break, we will go to Leinster on March 23 in a game that is massive for us and will provide us with the benchmark of where we are and where we can hope to go.

In the meantime, I took in a Scotland training session at Murrayfield on Tuesday, and I was highly impressed.

Next up for the Scots is the visit of Wales, and our interim head coach Scott Johnson has swapped our two Glasgow stand-offs, with Duncan Weir starting and Ruaridh Jackson dropping to the bench.

Duncan's impressive performance for Glasgow against Cardiff last Friday has swung things his way, and I have every confidence he has the maturity to impress.

While Ruaridh will be disappointed, he will be aware it is very much horses for courses.

Undoubtedly, the competition will make him even more determined to reclaim his starting place for the finale at the Stade de France.

Ruaridh's hopes were not helped by the type of game Scotland had with Ireland when I believe he only touched the ball on 12 occasions, compared to the average of between 50 and 60 in Tests for a stand-off.

But, for Duncan to gain his first start at Murrayfield against the Grand Slam champions is something he will never forget.

I am also delighted to see Ryan Wilson coming into the matchday 23, and that is fitting reward for his recent outstanding performances for both Scotland 'A' and Glasgow.

One area I will be paying special attention to on Saturday is the front row battle between our own Ryan Grant and the Welsh tight-head Adam Jones.

If Ryan can get the better of Jones, that will be a massive boost for the Scotland pack in the set-piece and also for his hopes of a British and Irish Lions place in the summer.

I believe the forecast is not good for Saturday, with sleet and rain coming our way and, if that is the case, there will be even more importance in Duncan's boot being at its most accurate.

There is no doubt Saturday will represent a huge test of where Scotland are against a resurgent Welsh side, so we must win a lot more ball than we did against the Irish.

It is looking like a fascinating game – and one Scotland can win.
