Gloucester had actually finished the regular 22-match, home-and-away season some 15 points ahead of Wasps at the top of the table and in every other English season since Leagues began would have been automatic champions.
But the change in format this season means that Gloucester's woeful performance in the heat of Twickenham in the Final means that their previous table-topping feats have counted for nothing.
However, Dallaglio sees no reason why Wasps should feel embarassed about their new champion status, pointing out that the format had been in place since the start of the season.
"After a performance like that, we thoroughly deserve it," Dallaglio told Sky Sports.
"We've won 17 of the last 19 games since Christmas. If that's not champion form, I don't know what is.
"We all knew what the rules of the competition were and we've worked very, very hard and finished the strongest team in the country.
"We didn't try to chase Gloucester's lead down as much as we would have done if it was just over 22 games.
"They played their better rugby towards the start of the season; we played our worst rugby at the beginning and have been getting better and better."
"It's not always been easy on the eye but we stuck at it and we thoroughly deserve this victory."
