"We do have a duty to play the game in the right way. We do want to play tough cricket, just like Australia do, but we have to make sure we stick to those boundaries and as captain I bear responsibility for that.
"Jeff has had a chat with me, but we all know the responsibilities we have when we pull on the shirt. No matter how much emotion there is in the game, we know how many people are watching us and we have got to behave appropriately.
"It shouldn't be a tea party, though. People pay good money to see tough, competitive cricket. That is what people love about the Ashes or any competitive cricket."
Cook himself appears impervious to verbal barbs, but that may not be the case for the new faces whom England could decide to blood here.
Gary Ballance and Ben Stokes are both possibilities for a place in the side, depending on the composition of the bowling attack.
An Ashes test is not the easiest place to make a debut, which is why Cook needs his senior players Kevin Pietersen, Ian Bell, Matt Prior, James Anderson and Graeme Swann, to perform for him here.
Pietersen, who made a double century here three years ago, averages more than 100 at the Adelaide Oval, so an average performance from him would suit England well. With Joe Root almost certain to bat at three, the middle order of Pietersen and Bell need to make telling scores if the team are to make more than 400, something they have not achieved for 17 innings.
"The senior players will have to lead the way if we are going to get back into the series," Cook said.
Watching the nets it was not immediately obvious who might deliver Cook the bounty he desires.
Bell retired hurt after being hit on the shoulder while facing throwdowns from Graham Gooch, the England batting coach, but was not thought to be a doubt for the test, just as Michael Clarke's decision to sit out yesterday's practice session with a sore ankle was not considered a serious problem.
The drop-in pitch was reportedly very dry, which is not how drop-ins usually begin a five-day match.
As such, Cook admitted that playing a second spinner was a serious consideration, something borne out when Monty Panesar took Mushtaq Ahmed, England's spin bowling coach, out to the middle to discuss field placings (there was a lot of pointing going on).
In the final test at the Oval, England played Chris Woakes, an all-rounder, to compensate for the extra spinner, something they could do again here with a fit-again Tim Bresnan or Ben Stokes.
Or they could just play Panesar and Swann as part of a four-man attack alongside Anderson and Stuart Broad, with Root to fill in a few overs.
It is most likely, unless they feel the pitch will dust up by day three, that Bresnan will return, in place of Chris Tremlett, and slot in alongside the usual trio, which would mean Ballance would almost certainly make his test debut.
Australia have only one spinner in their squad, though Steve Smith can bowl some wrist-spin, but it is not the slow stuff England's batsmen will be worried about. Instead, all eyes will be on Mitchell Johnson and how much pace and bounce he can extract from what is traditionally a benign surface.
In the nets yesterday, Chris Rogers took a battering from Johnson and looked relieved when it was over.
If England's batsmen can come off wearing the same expression, but with runs to their name, the Ashes may be yet retained.
