Norwich boss Hughton: Vaughan must build on preseason form
Vaughan struck twice in their friendly defeat to Hertha Berlin.
Hughton told the Pink 'Un: "He capitalised on the fact we had put out a side after the break who were fresher. He has had a difficult period recently with injury but pre-season is not just important for him but for everybody. For the lads who ended last season injured of course this is a key period for them but its about sustaining the fitness levels for every individual in the squad."
