Scotland wing Sean Lamont is frustrated the team have not quite been good enough in defeats to New Zealand and South Africa.
Andy Robinson's men followed their 51-22 defeat by the All Blacks with a 21-10 loss to the Springboks at Murrayfield, but Lamont thinks they could have made life easier on themselves.
Lamont felt their tackling was too high and not strong enough as South Africa dominated territory in the first 50 minutes, when all of their points were scored.
Next up for Scotland are Tonga at Pittodrie and Lamont insists it is not all doom and gloom as there are positives to take from their defeats going forward.
"Frustration is the main thing," said Lamont. "We are doing well in certain areas but we are just not getting the balance in defence.
"We are getting in people in the right place to make the tackles but we are just not hitting them hard, dropping them down and knocking them over.
"South Africa got the momentum going forward and they are very good at that and are going to punish you for that.
"The physical side of things is something that should never have let us down, but unfortunately it has been the same the last two weeks. We should have been confident because the summer tour went so well.
"They are number one and two in the world for a reason but the scorelines should not have been quite so big. We should have been pushing them closer and working them harder.
"There are plenty of positives, we are scoring tries now but we need to get that balance spot-on of having a rock-solid defence and an attack that can cut. We are just not there yet."
