Lake, who like Morgan missed the Six Nations because of injury, excelled on his return to the side in the summer, despite defeat against South Africa at Twickenham and two losses against the Wallabies.
“It was amazing,” said Lake.
“Any time you get to play for your country, it’s an honour.
“We would have liked a result to go our way. I think we should have had it, especially in the second Test against Australia.
“We outplayed them and were a better team, but a few costly mistakes awarded them tries.
“The summer on the whole was amazing with the group of boys and the experience I had being in Australia for the first time.”
Wales have slipped to 11th in the world rankings and have lost nine consecutive internationals.
“The public are right to want results, that’s why we play the game and we should be putting some of these teams away,” said Lake.
“We’re not far away. Some of the rugby we created in Australia was good, we just didn’t finish it off.
“It’s that last 5% we need now and the more time we have together, the better we’re going to get.
“But we can’t keep using it as an excuse for results that should have gone our way.
“At some point, we have to start winning these games and seeing positive results.
“It’s always going to be the same message. We might play nice rugby but if we don’t get results, it doesn’t matter.”
