Grimes said: “The biggest disappointment so far is the fact that we’ve not scored many points. We have not scored any tries in two games and our cumulative score has really been pretty bad.

“We know we are capable of breaking down defences and we have done that to a certain extent but we just haven’t finished them off.

“Although we put in a lot of physical effort against France, we need to be more clever in what we are doing. You have got to put in the right kind of effort, otherwise it is wasted.

“We lost out in Paris through a lack of tactical know-how and there were some individual skills in which the French had a slight edge over us.

“A lot of the French pack are big players but they are clever players as well and there are certain aspects at the breakdown that they are pretty good at. We try to learn off these teams because that is where we lost it.

“But we have made some slight changes in training with tactics and different moves and we have tweaked a few things here and there, so we are really looking to score some tries against Wales.”

Grimes temporarily escaped the pressure of the Scotland set-up when he had a week off down at his club side Newcastle Falcons and although the ex-Watsonians player was glad of the break, he admitted it was a case of jumping out of the frying pan and into the fire.

He said: “It is always great to be with the Scotland team but sometimes sitting in a hotel for two weeks, no matter what profession you are in, makes you feel a bit bunged up.

“So it was good to get home and enjoy the home comforts and catch up.

“But it was not a relief to get away back to Newcastle because we are fighting a relegation battle so it is tough in both camps at the moment.

“But it’s back to business now and looking forward to this game against Wales.

“There is pressure on us but that comes from losing two games in a row rather than the fact that Wales is a winnable game.

“We have lost the last two games heavily so we really need to prove a point and prove we are a good side.”
