Gavin Henson says the Ospreys want revenge over Leicester in Sunday's Heineken Cup tie after unfair tactics in last week's 30-12 Tigers win. The Ospreys led 12-6 at half-time in Welford Road before a fight back.
"The comeback was due to their cheating in and around the ruck. They got out of difficult areas and scored tries from it," Henson told BBC Sport Wales.
"They got away with it, but we're aware of it now. We feel hurt and cheated and will let them know about it on Sunday."
Henson's typically controversial opinions found backing from Ospreys coach Lyn Jones, who witnessed the Tigers blast through the centre of his side's ruck defence for tries after Welsh players were cleared out.

"Leicester came out with different tactics and a different mind set in the second half," said Jones.
"Perhaps the launderette people can shrink our jerseys back to size because they got pulled out of all shape and size in those 40 minutes.
"It was very disappointing. We've all done it as players and had it done to us, and in the good old days you would have taken the law into your own hands.
"Now, if it repeatedly happens - as it did at Welford Road - you expect the referee to take action and show cards.
"I'm not saying it's why we lost last week, but the tactics led to a few scores.
"We have to turn up on Sunday feeling hard done by and come out determined to put it right.
"We must take no prisoners, take the game to Leicester and try to drag them into an open, expansive game."
If the Ospreys' words are likely to fuel passions ahead of the game in Swansea, Anglo-Welsh tensions will be further inflamed by Llanelli Scarlets' pre-match rhetoric ahead of their game with Wasps at the Causeway Stadium on Sunday.
The Scarlets have been angered by Wasps' reaction to their 21-13 loss at Stradey Park last week, with Lawrence Dallaglio blasting his team for what he described as a sub-standard performance.
"It was an interesting reaction, they've been very hard on themselves and said they didn't perform," Jenkins told BBC Sport Wales.
"That's surprising because we've got a great track record ourselves in the Heineken Cup and have been very defiant at home over the years.
"We're mentally strong, and that has only been boosted by last week's win.
"Maybe Wasps' expectation was too big. We had looked at the game tactically and applied pressure to their weaknesses.
"It's not just Wasps, maybe it's an English thing but it never ceases to amaze me.
"There's always an expectation when an English side come down to play in Wales that they have a divine right to win irrespective of how they play.
"That's not the case, you have to be a good team to win down here."
