"This is a three-test campaign and nothing surprises you in this industry.
"Quade is a huge talent; we understand what he is capable of," Deans said.
"We've now settled on the squad and we'll get on with our opportunity."
Deans said watching Saturday night's match between the Queensland Reds captained by Cooper and the touring Lions "probably just reaffirmed where we're at".
Meanwhile, Lions coach Warren Gatland has distanced himself from spying allegations levelled at the Wallabies.
Gatland yesterday moved to clarify comments he made after the Lions' 22-12 win over Queensland which seemed to suggest the Australian camp had secretly taped a closed training session in Perth last week.
He denied he alleged the Wallabies were directly involved when a spectator was chased out of training by fitness staff and made to delete footage.
"I said that the Australian team were videoing us in our game [against the Western Force] last week in Perth from behind the field which they are perfectly entitled to," he said. "I said we threw some punter out of training [at nib Stadium] that was videoing us, that was all.
"If Australia try to video us, I've got no worries about that so there's no allegations of spying.
Gatland hosed down the controversy after naming his team for tomorrow night's clash with Combined Country at Newcastle, the tourists' fourth tour match.
Midweek lineup
Lions team to play Combined Country at Newcastle tomorrow: Sean Maitland, Alex Cuthbert, Brian O'Driscoll (c), Jamie Roberts, George North, Stuart Hogg, Conor Murray, Jamie Heaslip, Justin Tipuric, Sean O'Brien, Ian Evans, Richie Gray, Dan Cole, Richard Hibbard, Alex Corbisiero.
