London Irish director of rugby Brian Smith is adamant the 31-9 scoreline flattered Leicester after the Exiles suffered another loss on Saturday.
Tigers built an early 14-0 lead before the Exiles managed to find a way back into matters. But a penalty from Toby Flood and two late converted scores gave Leicester a handsome win on paper.
"I'm really disappointed as we came up short again. I'm proud of the boys' effort and we deserved a bonus point, so to come away with nothing was harsh," said Smith after the loss.
"The third try was the game-breaker for us. There were clear hands in the ruck to wrestle the ball free to give Leicester their opportunity and when the penalty try was awarded it was game set and match."
Smith also lamented the fact that England hooker Tom Youngs was not punished for his charge into a ruck.
"Tom Youngs shouldn't have played the full 80 minutes," said Smith.
"There were no arms involved and it was a shoulder charge which nearly took Declan Danaher's head off. It was perhaps a red-card offence and the citing commissioner will have to have a look at it."
