London Wasps skipper Lawrence Dallaglio claims the newly crowned European champions lag behind NEC Harlequins when it comes to resources.
The 36-year-old former England captain lifted the Heineken Cup for the second time in his career following Sunday's 25-9 triumph over Leicester.
But he believes Wasps must match Quins if they are to sustain their success for another five years.
"Our job is to win rugby matches and that is all we have concentrated on," he said. "We need to make sure we sort ourselves off the field and compete with the likes of Leicester, Northampton and Harlequins, who have great facilities and resources."
