England Knights clinched the Alitalia European Cup with a 62-24 victory over Scotland.
Pressure
Purtill was particularly pleased with the way his squad coped with the late disruption to their preparations.
"They've put a bit of pressure on the next group of Knights coming through - we talk about setting the standard for the next groups to follow and they've certainly raised the bar," he added.
"We were unfortunate during the week to lose Shaun Lunt and Luke Gale to injury and Michael Lawrence to illness and that probably disjointed us a little in our preparation but the lads pulled through together and showed great spirit.
"A special mention goes to Ben Currie, who came on board late and showed the right attitude and the right spirit to be involved and that's been a key factor in this group."
