Scotland flanker Ryan Wilson has been impressed with Scotland's potential in the back row since the emergence of Hamish Watson and Magnus Bradbury.
Watson and Bradbury both started in Scotland's win over Argentina on the weekend and Wilson says their performances have pushed him to work harder in training.
"We're bringing through plenty of back-rows right now and we're all pushing each other on," Wilson said.
"Magnus did fantastic at the weekend when he played. That's just credit to the depth Scottish rugby is bringing through.
"It certainly (encouraging) when you see someone coming through and pushing you that bit more.
"It pushes you in training and means you've got to work harder. You can never rest on your laurels here. You've got to keep working to keep that shirt on your back.
"The depth throughout the squad is growing and growing. Every season there is another couple of players who come in and do so well.
"It's credit to the Scottish mentality that when you get your chance, you take it. Every one of the new boys who have come in to the squad have done that."
Wilson was a replacement against Argentina, having started at number eight the previous week against the Wallabies.
