Harlequins boss Conor O'Shea admitted his side did not deserve to beat Wasps this afternoon.
It took a late Sam Smith try to secure the points for Quins in a game their rivals dominated for long spells.
But O'Shea believes his side will look more of a threat when conditions dry out - hopefully in time for next weekend's home game against Dean Richards' Newcastle Falcons.
He said: "The best team lost today, without any doubt. We didn't play with any shape or form, and we won't be playing like that again.
"We didn't hold on to the ball well enough, but all credit to the players for displaying mental toughness and hanging in there to sneak a win at the end.
"We are still in the top four, and playing conditions will improve before we play Newcastle next week. At the end of the season, this will be a golden result for us."
