Cardiff Blues fly-half Robinson has profited from the failure of rival Ceri Sweeney to take the chance offered him by Ruddock in the 50-44 first Test defeat at Tucuman last weekend.

And the coachs actions have sent a clear message that failure to perform will lead to losing the coveted red jersey.

Ruddock said, I think Ceri didnt have his best game for Wales last weekend. Hes a really talented guy and has a lot to offer, but on the day it didnt go well for him and these things happen from time to time. Nicky took over from him in the second half and made a good impact and the reality is that he deserves to have a run.

Its more so the case at this level that the competition for places is going to be stronger. At club level the gaps might be wider between the number one and number two players in their positions. But all of our squad are talented players involved at regional level.

They have all had international experience and its good that we have competition. That is what we are trying to generate. The message is loud and clear. We want good performances otherwise your place could be in jeopardy.

Robinson must now provide the tactical nous to ensure he does not suffer the same fate.

Ruddock said: Nicky made quite an impact when he came on and I have to find out about him. He has a lot of ability and gets the line moving. He now needs to show us that he has the maturity to run a Test match from fly-half.

If possession slows down so much that we cant use it, I want Nicky to turn them and put the ball in the corner.

"I want him to go out and play his game and use our big centres to get us going forward. If we get quick ball, I want him to get the ball wide and if its slow ball, turn the opposition. Its a pretty simple formula.

Nicky has an opportunity  lets see if he can take it and Im sure he will.
