Saracens lock George Kruis reckons England had maintained professionalism during their joint training session with Wales in Bristol.
The nations' packs warmed-up for their opening autumn internationals by drilling their set-pieces under the gaze of referee Nigel Owens after Steve Borthwick brokered an arrangement between the camps.
There were concerns about the intensity arising between the players but the session that included a completion of 12 scrums and 16 line-outs over 40 minutes went out successful with both the teams gaining valuable exposure.
"There was definitely intent there. I'd say we were professional enough to control ourselves and understand it was a training tool rather than a smash-up on the Monday of a Test week," Kruis said.
"We went in there trying to get a squeeze on and as much out of it as we could. We wanted to win every scrum and wanted the intent, but it also gave ourselves the opportunity to trial a few things and see where we're at.
"It was under Test match intensity, but was a good tool for us. It definitely lets us know where we're at as a pack and has shown us things that maybe we need to work on for this week.
"Because it's happened nice and early in the week, it's given us time to fix up and tweak anything that we need to."
The 27-year-old also urged the red rose team to be wary of the set-piece challenge that they might face when taking on Argentina in the opening game of the autumn internationals.
"Argentina are a huge set-piece team and they had a good go at us down in Argentina in the summer, especially at the scrum, so there will be a huge focus on that.
"They're a proud and physical team and we need to get our heads around that and come out with the same, if not more, aggression."
Meanwhile, England scrum coach Neal Hatley said Wasps wing Elliot Daly is being assessed on his return from a knee injury and a call on his participation will be taken in the coming days.
"Elliot is in camp and being assessed. We've been pretty busy so we'll find out more about him later in the day," said Hatley.
